Enterprise Server 3.12 release notes

HIGH: An attacker could bypass SAML single sign-on (SSO) authentication with the optional encrypted assertions feature, allowing unauthorized provisioning of users and access to the instance, by exploiting an improper verification of cryptographic signatures vulnerability in GitHub Enterprise Server. This is a follow up fix for CVE-2024-9487 to further harden the encrypted assertions feature against this type of attack. Please note that encrypted assertions are not enabled by default. Instances not utilizing SAML SSO, or utilizing SAML SSO authentication without encrypted assertions, are not impacted. Additionally, an attacker would require direct network access as well as a signed SAML response or metadata document to exploit this vulnerability.

HIGH: An attacker could achieve container escape and privilege escalation to root by exploiting a path collision and arbitrary code execution via the ghe-firejail path. GitHub has requested CVE ID CVE-2024-10007 for this vulnerability, which was reported via the GitHub Bug Bounty program.

This error message mbind: Operation not permitted was repeatedly showing in the /var/log/mysql/mysql.err MySQL logs.

When saving settings in the Management Console, the configuration run would stop if the enterprise-manage process was restarted.

A missing configuration value prevented Dependabot from creating group update pull requests.

On an instance with GitHub Actions enabled, some maintenance tasks could fail due to incomplete upgrade steps during previous upgrades to new releases of GitHub Enterprise Server.

The initial setup certificate generation in AWS took longer than expected due to fallback to private IPs. The time for this fallback has been reduced.

If the primary instance was unreachable, running ghe-repl-stop --force on a replica would fail during the config apply run.

When restoring from a backup, repositories that had been deleted in the last 90 days were not completely restored.

Restoring Git repositories using backup-utils occasionally failed.

Organizations were limited to using 100 Actions organization variables instead of 1,000.

Some customers upgrading from 3.12 to 3.13 or to 3.14 may experience issues with undecryptable records during the upgrade. This issue has now been resolved. We recommend you read "Undecryptable records."

For instances deployed on AWS, the default settings for Chrony NTP synchronization have been aligned with AWS's suggested default configurations.

Custom firewall rules are removed during the upgrade process.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. See "Solución de problemas de acceso a la Consola de administración."

The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn't required, and outputs an error instead of a warning.

On an instance hosted in AWS, system time may lose synchronization with Amazon's servers after an administrator reboots the instance.

On an instance with the HTTP X-Forwarded-For header configured for use behind a load balancer, all client IP addresses in the instance's audit log erroneously appear as 127.0.0.1.

In some situations, large .adoc files stored in a repository do not render properly in the web UI. The raw contents are still available to view as plaintext.

Repositories originally imported using ghe-migrator will not correctly track GitHub Advanced Security contributions.

The reply.[HOSTNAME] subdomain is falsely always displaying as having no SSL and DNS record, when testing the domain settings via the Management Console without subdomain isolation.

Admin stats REST API endpoints may timeout on appliances with many users or repositories. Retrying the request until data is returned is advised.

If a hotpatch upgrade requires the haproxy-frontend service to be restarted, the restart will hang if there are existing long-lived connections, such as browser web sockets or Git operations. No new connections will be accepted for up to 5 minutes. Any existing unfinished connections at this time will be disconnected.

When restoring from a backup snapshot, a large number of mapper_parsing_exception errors may be displayed.

Services may respond with a 503 status due to an out of date haproxy configuration. This can usually be resolved with a ghe-config-apply run.

MEDIUM: Malicious URLs for SVG assets provided information about a victim user who clicked the URL, allowing an attacker to retrieve metadata belonging to the user and use it to generate a convincing phishing page. This required the attacker to upload malicious SVGs and phish a victim user to click the URL for the uploaded asset. GitHub has requested CVE ID CVE-2024-9539. This vulnerability was reported via the GitHub Bug Bounty program.

HIGH: An attacker could bypass SAML single sign-on (SSO) authentication with the optional encrypted assertions feature, allowing unauthorized provisioning of users and access to the instance, by exploiting an improper verification of cryptographic signatures vulnerability in GitHub Enterprise Server. This was a regression introduced as part of follow-up remediation from CVE-2024-4985, which resulted in a new variant of the vulnerability. Please note that encrypted assertions are not enabled by default. Instances not utilizing SAML SSO, or utilizing SAML SSO authentication without encrypted assertions, are not impacted. Additionally, an attacker would require direct network access as well as a signed SAML response or metadata document. GitHub has requested CVE ID CVE-2024-9487. This vulnerability was reported via the GitHub Bug Bounty program.

HAProxy reloading was failure prone, which could lead to failed Git operations. This reloading process has been replaced with a more resilient Systemd process.

An unhandled nil value when configuring Actions storage with AWS S3 via OIDC configuration in the terminal could cause an error.

On an instance with secret scanning enabled, the custom pattern page would not load because dry run results were tied to a deleted repository.

The "List teams" API endpoint returning duplicate results when paginating.

A model with no URL could cause a ghe-migrator import to fail.

Restore could fail when restoring MySQL using backup-utils.

The ghe-remove-node command will display the log file location when running in quiet mode.

Pre-receive hook environments can use the clone3() system call.

The creation, deletion, or change in visibility of a gist has been added to the audit log.

Custom firewall rules are removed during the upgrade process.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "Solución de problemas de acceso a la Consola de administración."

When restoring from a backup snapshot, a large number of mapper_parsing_exception errors may be displayed.

Services may respond with a 503 status due to an out of date haproxy configuration. This can usually be resolved with a ghe-config-apply run.

MEDIUM: An attacker could steal sensitive information by exploiting a Cross-Site Scripting vulnerability in the repository transfer feature. This exploitation would require social engineering. GitHub has requested CVE ID CVE-2024-8770 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could push a commit with changes to a workflow using a PAT or OAuth app that lacks the appropriate workflow scope by pushing a triple-nested tag pointing at the associated commit. GitHub has requested CVE ID CVE-2024-8263 for this vulnerability, which was reported via the GitHub Bug Bounty program.

HIGH: A GitHub App installed in organizations could upgrade some permissions from read to write access without approval from an organization administrator. An attacker would require an account with administrator access to install a malicious GitHub App. GitHub has requested CVE ID CVE-2024-8810 for this vulnerability, which was reported via the GitHub Bug Bounty Program. [Updated: 2024-11-07]

For instances deployed on AWS with IMDSv2 enforced, fallback to private IPs was not successful.

A config apply run may not have been properly applied due to calls being made to Nomad before it was ready to accept connections. When this occurred, the Error querying agent info: failed querying self endpoint: Get "http://127.0.0.1:4646/v1/agent/self" error was written to the /data/user/common/ghe-config.log file.

ghe-storage-find was sometimes unable to identify a data disk.

After upgrading the relevant GHES version, the resolvconf service failed to start due to a missing directory.

When configuring a high availability replica and during the database seeding of a MySQL replica node, restarting the nomad service could time out. Consequently, when MySQL replication attempted to start an error was reported, and setting up replication failed.

Placing Nomad jobs would not allow retries in cases when Nomad wasnt available yet.

On an instance in a cluster configuration, the ghe-cluster-status command returned an error if a soft-deleted repository had a checksum mismatch.

Some repositories could miss spokes information after restoring in a clustering topology due to unrescued exceptions.

After a user created a Projects Insights chart with time as the X-axis, the chart became hidden and inaccessible.

The CommandPalette component no longer displays repository information on 404 pages, preventing the leakage of private repository information for users without access.

Custom links to other repositories displayed incorrect breadcrumbs.

A bug introduced in 3.12 which prevented the search input in the global navigation from displaying a dropdown of search suggestions has been fixed. The search input functionality prior to 3.12 has been restored, and users are once again able to see and submit suggested search queries, including scope suggestions.

When a GitHub App installation had all repositories installed individually, it was not possible to remove the repositories from the selection.

Some custom pattern matches were incorrectly filtered during post-scan filtering. You may want to edit and republish your custom patterns. You can manually republish custom patterns with the following command: ghe-secret-scanning jobs queue custom-patterns republish --custom-pattern-id=?. Outdated alerts caused by edits during custom pattern backfills have been fixed in version 3.13 and above.

For instances deployed on Amazon Web Services (AWS), site administrators can configure regional AWS STS endpoints for OIDC from the Management Console.

Custom firewall rules are removed during the upgrade process.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "Solución de problemas de acceso a la Consola de administración."

On an instance hosted in AWS, system time may lose synchronization with Amazon's servers after an administrator reboots the instance.

On an instance with the HTTP X-Forwarded-For header configured for use behind a load balancer, all client IP addresses in the instance's audit log erroneously appear as 127.0.0.1.

In some situations, large .adoc files stored in a repository do not render properly in the web UI. The raw contents are still available to view as plaintext.

Repositories originally imported using ghe-migrator will not correctly track Advanced Security contributions.

The reply.[hostname] subdomain is falsely always displaying as having no ssl and dns record, when testing the domain settings via management console without subdomain isolation.

Admin stats REST API endpoints may timeout on appliances with many users or repositories. Retrying the request until data is returned is advised.

If a hotpatch upgrade requires the haproxy-frontend service to be restarted, the restart will hang if there are existing long-lived connections, such as browser web sockets or Git operations. No new connections will be accepted for up to 5 minutes. Any existing unfinished connections at this time will be disconnected.

When restoring from a backup snapshot, a large number of mapper_parsing_exception errors may be displayed.

Services may respond with a 503 status due to an out of date haproxy configuration. This can usually be resolved with a ghe-config-apply run.

Users can view the app state of gists, networks, and wikis in the spokesctl info output, enhancing visibility into the status of these elements. Additionally, spokesctl check can diagnose and, in most cases, fix empty repository networks, improving network management.

CRITICAL: On GitHub Enterprise Server instances that use SAML single sign-on (SSO) authentication with specific IdPs utilizing publicly exposed signed federation metadata XML, an attacker could forge a SAML response to provision and/or gain access to a user account with site administrator privileges. GitHub has requested CVE ID CVE-2024-6800 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could update the title, assignees, and labels of any issue inside a public repository. This was only exploitable inside a public repository, and private/internal repositories were not affected. GitHub has requested CVE ID CVE-2024-7711 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could disclose the issue contents from a private repository using a GitHub App with only contents: read and pull requests: write permissions. This was only exploitable via user access token, and installation access tokens were not impacted. GitHub has requested CVE ID CVE-2024-6337 for this vulnerability, which was reported via the GitHub Bug Bounty program.

Packages have been updated to the latest security versions.

During hotpatching and sometimes when applying configuration changes, a configuration run to upgrade the GitHub Actions service was unnecessarily triggered. The GitHub Actions service will only be upgraded in GitHub Enterprise Server feature releases.

On an instance with GitHub Actions enabled, during a hotpatch upgrade, a race condition could block various upgrade activities.

The ghe-config-apply process made an unnecessary number of connections to Redis.

Upgrading the Dependency Graph sometimes failed due to outdated data from go.sum manifests.

Restarting the resolvconf service would not correctly update the contents of /etc/resolv.conf.

Instances installed on Google Cloud Platform (GCP) could have their hostname overwritten by GCP when a hotpatch was applied.

The minimum password requirements for Management Console users and the root site administrator required an upper case character when providing a password with a minimum of 8 characters, contradicting the documentation and password hint.

The ghe-migrations utility for visualizing migrations did not work due to a regression. Administrators can now run ghe-migrations to view the progress and status of github migrations, or run ghe-migrations --all to view progress on all services.

On an instance with subdomain isolation enabled, configuration runs created subdomains for ChatOps services, such as slack.HOSTNAME and teams.HOSTNAME, regardless of whether the service was enabled.

During support bundle generation or when running ghe-diagnostics, filesystem usage for the Elasticsearch data directory was not be included.

On an instance with GitHub Actions enabled, due to an insufficient wait time, MS SQL and MySQL replication could fail with the error message Failed to start nomad service!.

Site administrators could not switch maintenance mode directly from "scheduled" to "on," or vice versa.

Some users were unable to delete project views.

On the repository settings page for GitHub Pages, users saw an option to upgrade to GitHub Enterprise to use GitHub Pages with private visibility.

When importing using ghe-migrator, team URLs containing dots were imported as-is, leading to 404s when attempting to view the imported teams. Dots in imported team URLs are now escaped to dashes.

Due to a regression introduced in a previous patch, for enterprises that use encrypted SAML assertions, SSO attempts failed with a digest mismatch error if the entire SAML response was signed, rather than just the assertions.

On an instance with subdomain isolation enabled, images served from a subdomain or external source did not render correctly in issues opened in the Projects side panel.

In tag input fields, such as when adding topics to a repository, pressing space did not start a new tag.

Running go get for a Golang repository with a directory structure that overlaps with GitHub UI routes failed

The wrong help link was displayed when push protection blocked a secret from the CLI.

For repositories with issues disabled, issue links were redirected to pull requests.

Fixes and improvements for the git core module.

In custom pre-receive hooks, the paths stored in environment variables that allow for newly pushed objects to be in a quarantine directory could be incorrectly interpreted as relative to a worktree instead of the Git directory, causing certain commands to fail to read from the repository. The variables now use absolute paths.

A corrupted entry in the Git audit log could cause out of memory errors.

Actions KPI logs are disabled by default to reduce log size.

When running ghe-support-bundle, the support bundle includes the Elasticsearch config.

Users can set their styling preference for link underlines in the web interface, on their "Accessibility" settings page.

Audit log events related to audit log streaming are available in the enterprise audit log page, and via audit log streaming.

Custom firewall rules are removed during the upgrade process.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "Solución de problemas de acceso a la Consola de administración."

If an instance is configured to forward logs to a target server with TLS enabled, certificate authority (CA) bundles that a site administrator uploads using ghe-ssl-ca-certificate-install are not respected, and connections to the server fail.

The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn't required, and outputs an error instead of a warning.

On an instance hosted in AWS, system time may lose synchronization with Amazon's servers after an administrator reboots the instance.

On an instance with the HTTP X-Forwarded-For header configured for use behind a load balancer, all client IP addresses in the instance's audit log erroneously appear as 127.0.0.1.

In some situations, large .adoc files stored in a repository do not render properly in the web UI. The raw contents are still available to view as plaintext.

After failing over an instance in a cluster configuration, Git pushes to the instance will fail. This issue impacts pushes from the command line as well as the web interface. To resolve this issue, contact GitHub Support.

On an instance in a cluster configuration, restoration of a backup using ghe-restore will exit prematurely if Redis has not restarted properly.

Repositories originally imported using ghe-migrator will not correctly track Advanced Security contributions.

Due to a known regression, operators will not be able to use the ghe-migrations visualizer to view the status of migrations during an upgrade. Instead, the operator can inspect the log files in /var/log/dbmigration to see the status and progress of migrations.

The reply.HOSTNAME subdomain is falsely displayed as having no SSL and DNS record, when testing the domain settings via the Management Console without subdomain isolation.

Admin stats REST API endpoints may timeout on appliances with many users or repositories. Retrying the request until data is returned is advised.

If a hotpatch upgrade requires the haproxy-frontend service to be restarted, the restart will hang if there are existing long-lived connections, such as browser web sockets or Git operations. No new connections will be accepted for up to 5 minutes. Any existing unfinished connections at this time will be disconnected.

The global search bar does not have suggestions enabled due to the redesigned navigation and pending new search experience.

When restoring from a backup snapshot, a large number of mapper_parsing_exception errors may be displayed.

Services may respond with a 503 status due to an out of date haproxy configuration. This can usually be resolved with a ghe-config-apply run.

On boot, the resolvconf service may fail to start because the /run/resolvconf directory does not exist when the service attempts to touch a file there, with the error:

/bin/touch: cannot touch '/run/resolvconf/postponed-update': No such file or directory

If this occurs, workaround this issue with the following commands — this change will persist on reboots, but not upgrades:

sudo sed -i.bak \
'/\[Service\]/a ExecStartPre\=\/bin\/mkdir \-p \/run\/resolvconf' \
/etc/systemd/system/resolvconf.service.d/local.conf

sudo systemctl daemon-reload
sudo systemctl start resolvconf 

[Updated: 2024-08-26]

These release notes previously indicated as a known issue that on GitHub Enterprise Server 3.12.8 when log forwarding is enabled, some forwarded log entries may be duplicated. The fix for this problem was already included in GitHub Enterprise Server 3.12.7. [Updated: 2024-09-16]

HIGH: An attacker could cause unbounded resource exhaustion on the instance by sending a large payload to the Git server. To mitigate this issue, GitHub has limited the count of "have" and "want" lines for Git read operations. GitHub has requested CVE ID CVE-2024-5795 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An improper privilege management vulnerability allowed users to migrate private repositories without having appropriate scopes defined on the related personal access token. GitHub has requested CVE ID CVE-2024-5566 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could have unauthorized access in a public repository using a suspended GitHub App via a scoped user access token. This was only exploitable in public repositories while private repositories were not impacted. GitHub has requested CVE ID CVE-2024-5816 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could execute a Cross Site Request Forgery (CSRF) attack to perform write operations on a victim-owned repository in GitHub Enterprise Server by exploiting incorrect request types. A mitigating factor is that the attacker has to be a trusted user and the victim has to visit a tag in the attacker's fork of their own repository. GitHub has requested CVE ID CVE-2024-5815 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could disclose the name of a private repository on the GitHub Enterprise Server appliance when the private repository has a deploy key associated to it. GitHub has requested CVE ID CVE-2024-6395 for this vulnerability, which was reported via the GitHub Bug Bounty program.

LOW: Instance administrators could see fine-grained personal access tokens in plaintext in the babeld and gitauth logs.

LOW: An attacker with read access to a project could use the REST API to view a list of all members in an organization, including members who had made their membership private. This vulnerability was reported via the GitHub Bug Bounty program.

LOW: An attacker could include MathJax syntax in Markdown to bypass GitHubs normal restrictions on CSS properties in Markdown. This vulnerability was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could disclose sensitive information from a private repository exploiting organization ruleset features. This attack required an organization member to explicitly change the visibility of a dependent repository from private to public. GitHub has requested CVE ID CVE-2024-6336 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could have unauthorized read access to issue content inside an internal repository via GitHub projects. This attack required attacker access to the corresponding project board. GitHub has requested CVE ID CVE-2024-5817 for this vulnerability, which was reported via the GitHub Bug Bounty program.

Packages have been updated to the latest security versions.

When an instance hosted on Azure was upgraded with a hotpatch, the upgrade failed with an rsync error.

On an instance with GitHub Actions enabled, remote blob storage could fill up with large amounts of data because cleanup jobs were skipped on old hosts.

The ghe-cluster-repl-status command could be run on instance configurations other than high-availability clusters, resulting in an incorrect or incomplete status.

The threshold set by server_rejoin_age_max for single-node GHES deployments was too low.

In some cases, commands run in an administrative SSH shell were not written to the audit log.

When an administrator submitted support data to GitHub Support, spokesd keys were incorrectly sanitized.

When log forwarding was enabled, some specific service logs, including babeld, gitauth, unicorn, and resqued, were duplicated.

During the initial boot of an instance, a data disk attached as /dev/sdb may not have been recognized as an available disk.

In a high availablity configuration, running ghe-repl-node multiple times from a node that did not have replication running had the potential to overwrite the configuration on the primary node.

Configuration history is only generated for instances in a cluster, high availability (HA) cluster, or standalone HA configuration. The current node must be a primary or replica node with replication running.

In some cases, the HAProxy kill_timeout setting caused service outages during upgrades or large transactions.

The ssh-audit-log.sh script did not effectively log SSH commands, and the ghe-sanitize-log.psed script inadequately sanitized password-related logs.

The default MSSQL timeout of 8 seconds sometimes caused issues during administrator activities. The default timeout has been increased to 30 seconds.

For an instance running on Microsoft Azure, the user disk service failed to start because the attached volume could not be found.

Establishing a new GitHub Connect connection could fail with a 500 error.

When using ghe-migrator to migrate a repository, the links for pull requests merge commits were not imported.

When a user used the REST API endpoints that returned secret scanning alerts at the repository or organization level with non-cursor-based pagination (for example, without before or after query parameters), the REST API endpoints for secret scanning returned incorrect Link headers.

On certain branch names, the branch info bar was causing frozen string errors.

On instances with SAML authentication configured, users were unable to sign out and became stuck in an infinite SAML SSO loop.

On instances with SCIM enabled, the administrator was unable to view users without an external identity record (for example, because they were provisioned before SCIM was enabled on the instance) in stafftools.

After navigating to a discussion, the link underline for the Discussions tab in the GitHub UI incorrectly appeared under the Settings tab heading.

On instances enrolled in the SCIM private beta, built-in authentication users can be added to organizations and teams. Organization owners will no longer see the misleading message that the organization membership is managed by the SAML identity provider when updating organization memberships.

Enterprise owners managed by an identity provider were asked to authenticate within GitHub when performing privileged actions.

On an instance that restricts emails to verified domains, secret scanning emails would sometimes be sent to an unverified domain.

In some cases, on the "Files" tab of a pull request, a comment on the first line did not render.

Some organizations were not recognized as part of an instance's enterprise account.

Some users would encounter an error when navigating to their personal security settings page at https://HOSTNAME/settings/security.

The SpokesSyncCacheReplicaJob could not initialize in some cases, resulting in an exception when handling the error.

In the sidebar menu that is displayed when a user clicks their profile picture, users who are not enterprise owners saw an "Enterprise settings" option, linking to the main page of an enterprise. This option is now labeled "Your enterprise".

On the "Code scanning" page of a repository, the branch filter did not correctly display all branches.

When including a .gitignore or README.md file on repository creation failed due to a ruleset or pre-receive hook, no error message displayed.

On an instance with a GitHub Advanced Security license, requests to the /enterprises/{enterprise}/settings/billing/advanced-security REST API endpoint could fail due to timeout.

On some instances, users were unable to save historical insights charts for Projects.

The setting to enable or view non-provider patterns was not available for public repositories.

Users viewing the alerts index page experienced inconsistencies in rendering the closed alert state.

Organizations named "C" were incorrectly routed to the GitHub Enterprise Server contact page instead of their organization page.

On an instance with a GitHub Advanced Security license, commits made by users who do not belong to an organization were not counted.

When servers responded with unsupported characters, webhook deliveries were not displayed in the UI.

Chat integrations required frequent reauthentication, as a result of new app installations overwriting previous ones.

On an instance in a cluster configuration, the ghe-spokesctl ssh command did not select the correct Nomad container when running a command within a Git repository.

On an instance with a GitHub Advanced Security license, disabling and re-enabling GitHub Advanced Security for an organization resulted in redundant scans of some repositories.

On an instance with a GitHub Advanced Security license, contributions were not tracked on public repositories.

On an instance with a GitHub Advanced Security license, the "adjust configuration" step failed when enabling code scanning with the default setup on self-hosted Windows runners.

Migration of the issue_edits table caused intermittent failures during the upgrade to GitHub Enterprise Server version 3.12, resulting in the error message ActiveRecord::ConcurrentMigrationError: Failed to release advisory lock. [Updated: 2024-08-14]

In a high availability configuration, users can only run ghe-config-apply or ghe-cluster-config-apply on a replica node if replication is already running (from ghe-repl-start). If replication isnt running on the node, the user will be instructed to start replication.

Configuration history has been extended. When ghe-config-apply, ghe-cluster-config-apply, or ghe-config-archive is run: secrets.conf is captured, a sha256sum for each of the current configuration files is included, the existing patch that is generated includes secrets.conf, and an additional sanitized patch that excludes secrets.conf is also generated.

The timeout for requests made to the REST API endpoints for secret scanning has been extended.

A more specific error message is shown when a non-provisioned user tried to sign in to an instance with SCIM enabled.

When a user changes a repository's visibility to public, the user is now warned that previous Actions history and logs will become public as well.

A more specific error message is shown when a deprovisioned user attempts signing into an instance with SCIM enabled.

In the audit logs, administrators can see more context for failed user authentication attempts using LDAP.

The system logs provide more context for authentication failures related to multi-factor authentication.

When using the ghe-webhook-logs utility, webhook delivery logs can be filtered by event and action. Users can use ghe-webhook-logs --event issues to filter by event, or ghe-webhook-logs --event issues.opened to filter by event and action.

To avoid excessive log volume and associated disk pressure, requests for GetCacheKey are no longer logged. Previously, the high frequency of these requests caused significant log accumulation.

Custom firewall rules are removed during the upgrade process.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "Solución de problemas de acceso a la Consola de administración."

If an instance is configured to forward logs to a target server with TLS enabled, certificate authority (CA) bundles that a site administrator uploads using ghe-ssl-ca-certificate-install are not respected, and connections to the server fail.

The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn't required, and outputs an error instead of a warning.

On an instance hosted in AWS, system time may lose synchronization with Amazon's servers after an administrator reboots the instance.

On an instance with the HTTP X-Forwarded-For header configured for use behind a load balancer, all client IP addresses in the instance's audit log erroneously appear as 127.0.0.1.

In some situations, large .adoc files stored in a repository do not render properly in the web UI. The raw contents are still available to view as plaintext.

After failing over an instance in a cluster configuration, Git pushes to the instance will fail. This issue impacts pushes from the command line as well as the web interface. To resolve this issue, contact GitHub Support.

On an instance in a cluster configuration, restoration of a backup using ghe-restore will exit prematurely if Redis has not restarted properly.

Repositories originally imported using ghe-migrator will not correctly track Advanced Security contributions.

Due to a known regression, operators will not be able to use the ghe-migrations visualizer to view the status of migrations during an upgrade. Instead, the operator can inspect the log files in /var/log/dbmigration to see the status and progress of migrations.

The reply.[hostname] subdomain is falsely always displaying as having no ssl and dns record, when testing the domain settings via management console without subdomain isolation.

Admin stats REST API endpoints may timeout on appliances with many users or repositories. Retrying the request until data is returned is advised.

If a hotpatch upgrade requires the haproxy-frontend service to be restarted, the restart will hang if there are existing long-lived connections, such as browser web sockets or Git operations.

Instance administration

• To ensure an instance's readiness for an upgrade to a new feature release of GitHub Enterprise Server, administrators can ensure that background tasks from a previous upgrade are complete using the ghe-check-background-upgrade-jobs command-line utility. For more information, see "Actualizar con un paquete de actualización" and "Utilidades de la ea de comandos."

• When backing up an instance in a cluster configuration using GitHub Enterprise Server Backup Utilities, the pre-flight routine includes a health check for all nodes and notifies administrators of any issues before the backup begins.

• The REST API's /manage/v1 endpoints have been expanded to include all the same operations as the /setup/api endpoints. The /setup/api endpoints will be deprecated in a future release of GitHub Enterprise Server. For more information, see the following articles in the REST API documentation.

  • "Puntos de conexión de API de REST para administrar GitHub Enterprise Server"
  • "Puntos de conexión de API de REST para la consola de administración"

• On an instance in a cluster configuration, administrators can use the ghe-remove-node command-line utility to remove a node from a cluster. This command evacuates data from the node's data services, marks the node as offline, and stops traffic being routed to the node, replacing the manual steps previously required to remove a node. For more information, see "Utilidades de la ea de comandos." [Updated: 2024-02-28]

• On an instance in a cluster configuration, administrators can more easily configure or tear down a high availability replica of the cluster. For more information, see the documentation for the following utilities in the "Command-line utilities" article:

  • ghe-cluster-repl-bootstrap
  • ghe-cluster-repl-teardown

  [Updated: 2024-03-25]

Authentication

• To manage work across different accounts and GitHub products, users can authenticate to the GitHub CLI with multiple accounts, then use the gh auth switch command to switch between active accounts. For more information, see gh auth login in the GitHub CLI manual.

GitHub Advanced Security

• The GitHub Advanced Security billing REST API and CSV download includes the email addresses for active committers. This provides information for insights into Advanced Security license usage across your business. For more information, see "Puntos de conexión de API de REST para facturación de empresa" and "Visualizar tu uso de GitHub Advanced Security".

• To make it easier for users to secure repositories, default setup for code scanning automatically attempts to analyze all languages supported by CodeQL. Users no longer need to manually include analysis of C, C++, C#, Java, or Kotlin when enabling default setup, and organization owners and security managers can enable analysis of these languages for multiple repositories in an organization. For more information about the languages and versions supported by CodeQL and code scanning, see "Establecimiento de la configuración predeterminada para el examen del código" and "Supported languages and frameworks" in the CodeQL documentation.

• Customers who use both GitHub Enterprise Server and GitHub Enterprise Cloud can ensure license usage for GitHub Advanced Security is calculated correctly by synchronizing license usage across deployments. Synchronization can be performed automatically, using GitHub Connect, or manually, using an export file. For more information, see "Sincornizar el uso de licencias entre GitHub Enterprise Server y GitHub Enterprise Cloud."

• For code scanning, this release of GitHub Enterprise Server uses version 2.15.5 of CodeQL by default. This version of CodeQL includes more up-to-date support for various languages, including C# 12, .NET 8, TypeScript 5.3, Java 21, and Python 3.12. For more information, see the changelog for CodeQL 2.15.5 in the CodeQL documentation.

• Code scanning with CodeQL has improved support for detecting vulnerabilities in C and C++ code, with queries available for detecting common memory-corruption vulnerabilities. These queries are in beta and subject to change. For more information, see ICYMI: improved C++ vulnerability coverage and CodeQL support for Lombok on the GitHub Blog.

• For repositories migrated to GitHub Enterprise Server from other platforms, to calculate active committers for GitHub Advanced Security license usage, GitHub only considers commits made after the migration date. Previously, historic commits were included in the calculation, and users needed to intervene manually to avoid consuming licenses unnecessarily. For more information, see "Acerca de la facturación de GitHub Advanced Security."

• To make the language overview on the tool status page more informative, users can directly specify Kotlin, C, and TypeScript as languages to be analyzed using the language property of a codeql.yml file. For example: language: [ 'kotlin' ]. These languages were already supported by CodeQL, but were previously treated as being part of the Java, CPP, and JavaScript languages respectively.

• To increase the coverage of secret scanning without needing to maintain custom patterns, users can configure secret scanning to detect non-provider patterns. Non-provider patterns are patterns such as private keys that tend to have a higher rate of false positives than high-confidence patterns. GitHub displays non-provider alerts in a different list from high-confidence alerts, making triaging a better experience for users. This feature is in beta and subject to change. For more information, see "Administración de alertas del examen de secretos."

Dependabot

• To debug issues with Dependabot, users can view logs for Dependabot job runs associated with version updates, security updates, and rebase updates. For more information, see "Visualización de registros de trabajos de Dependabot."

• Users can choose how to respond to Dependabot alerts automatically by setting up custom auto-triage rules in repositories or organizations. Auto-triage rules provide control over whether an alert is ignored, is snoozed, or triggers a pull request for a security update. Users can also use a rule created by GitHub to automatically dismiss low-impact issues in npm dependencies. Auto-triage rules are in public beta and subject to change. For more information, see "Acerca de Evaluación de prioridades automática de Dependabot."

• Dependabot version updates have improved support for dependencies in NuGet, the package manager for .NET. Improvements include better support for implicit dependencies and peer dependencies. For more information about supported package managers, see "Acerca de las actualizaciones a la versión del Dependabot."

GitHub Actions

• For self-hosted GitHub Actions runners on this GitHub Enterprise Server release, the minimum required version of the GitHub Actions Runner application is 2.311.0. See the release notes for this version in the actions/runner repository. If your instance uses ephemeral self-hosted runners and you've disabled automatic updates, you must upgrade your runners to this version of the Runner application before upgrading your instance to this GitHub Enterprise Server release. [Updated: 2024-04-25]

• Users can set up organization-wide rules to enforce their CI/CD workflows, ensuring workflows pass before pull requests can be merged into target repositories. You can fine-tune your rule by selecting a specific branch, tag, or SHA, and provide maximum control over the version expected to run. To reduce risk, you can "evaluate" workflow rules to validate rules are working correctly. For more information, see "Reglas disponibles para conjuntos de reglas".

• GitHub Actions developers can use GitHub Actions Importer to plan, forecast, and automate the migration of existing CI/CD pipelines from Bamboo Server, Bamboo Data Center, and Bitbucket. Developers can migrate their Bamboo and Bitbucket pipelines to GitHub Actions using the GitHub CLI or IssueOps. For more information, see "Migración desde canalizaciones de Bitbucket con el importador de acciones de GitHub" and "Migración desde Bamboo con el Importador de Acciones de GitHub".

• Actions environments support defining selected tag patterns to restrict deployments. Administrators who want to have more secure and controlled deployments can specify selected tags or tag patterns on their protected environments. For more information, see "Administrar entornos para la implementación".

Community experience

• To tailor information to users' needs, users are prompted to sign in to access the GitHub Support portal. For customers with an enterprise account on GitHub.com, we encourage users to sign in to an account with support privileges for the enterprise. For more information, see "Administrar los derechos de soporte para tu empresa." Users who cannot sign in to an account on GitHub.com can still access the portal by verifying an email address.

• To help users find answers to their questions more quickly, GitHub Copilot is integrated into GitHub Support. Users can choose to chat with Copilot instead of creating a ticket on the "Get help with GitHub" contact form. Copilot has been trained on the GitHub Enterprise Server documentation on GitHub Docs. This feature is in public beta and subject to change.

Projects

• Project templates for organizations are generally available. Users in an organization can create a template to share a pre-configured project with other people in your organization as the base for their projects. For more information, see "Administración de plantillas de project en la organización".

• Users can access Projects from from the global navigation menu. This page can be used to find projects you've recently viewed or created, regardless of the organization or where they are located. For more information, see "Búsqueda de projects".

GitHub Discussions

• Users can filter for answered or unanswered discussions with the GraphQL API by using the answered property. For more information, see "Utilizar la API de GraphQL para los debates."

Pull requests

• Users can merge pull requests without needing to wait for status checks to pass by adding a pull request to a merge queue. The merge queue ensures that the changes in the pull request will pass all required status checks when applied to the latest version of the target branch. A pull request is merged automatically once it reaches the front of the queue. This feature is particularly useful on branches where pull requests are merged frequently. For more information, see "Administración de una cola de fusión mediante combinación."

Markdown

• Users can highlight information using Markdown alerts. Alerts are displayed with distinctive colors and icons, and include notes, tips, warnings, and more. For more information, see "Sintaxis de escritura y formato básicos."

Accessibility

• The web interface for GitHub Enterprise Server has been redesigned to provide a more intuitive, responsive, and accessible navigation experience. Changes include:

  • Breadcrumbs to help users navigate the site more efficiently
  • Menus to quickly access a user's top repositories and teams
  • A more accessible navigation experience, including more consistent keyboard navigation and improvements to code search

  For more information, see Exploring GitHub with the redesigned navigation on the GitHub Blog. Note that the redesigned navigation is now generally available.

• The comment field in issues, discussions, and pull requests has been redesigned for easier use across different screen sizes, and for better integration with assistive technology such as keyboard navigation and screen readers.

Field names for some service logs on GitHub Enterprise Server have changed as part of GitHub's gradual migration to internal semantic conventions for OpenTelemetry. Additional field names were changed in GitHub Enterprise Server 3.9, 3.10, and 3.11. If any tooling or processes in your environment rely on specific field names within logs, or log entries in specific files, the following changes may affect you.

• level is now SeverityText.
• log_message, msg, or message is now Body.
• now is now Timestamp.
• Custom field names such as gh.repo.id or graphql.operation.name use semantic names.
• Log statements that the instance would previously write to auth.log, ldap.log, or ldap-sync.log now appear in containerized logs for github-unicorn if the statement originated from a web request, or in logs for github-resqued if the statement originated from a background job. For more information about containerized logs, see "Acerca de los registros del sistema."

For a full list of mappings, download the OpenTelemetry attribute mapping CSV for GitHub Enterprise Server 3.9, 3.10, 3.11, and 3.12.

On an instance with GitHub Advanced Security and code scanning enabled, the bot that posts comments and annotations for code scanning alerts on pull requests has been renamed from github-code-scanning to github-advanced-security.

The REST API's /rate_limit endpoint is now subject to rate limits. Requests will not consume the primary rate limit quotas for the authenticated user. However, making a very high number of requests in a short period of time will trigger the secondary rate limits if secondary rate limits are enabled on your instance. For more information, see "Puntos de conexión de la API de REST para los límites de velocidad" in the REST API documentation and "Configuración de los límites de frecuencia."

TCP port 9103 is opened for future administrative features related to support for Prometheus scraping.

Custom firewall rules are removed during the upgrade process.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "Solución de problemas de acceso a la Consola de administración."

If an instance is configured to forward logs to a target server with TLS enabled, certificate authority (CA) bundles that a site administrator uploads using ghe-ssl-ca-certificate-install are not respected, and connections to the server fail.

The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn't required, and outputs an error instead of a warning.

On an instance hosted in AWS, system time may lose synchronization with Amazon's servers after an administrator reboots the instance.

On an instance with the HTTP X-Forwarded-For header configured for use behind a load balancer, all client IP addresses in the instance's audit log erroneously appear as 127.0.0.1.

In some situations, large .adoc files stored in a repository do not render properly in the web UI. The raw contents are still available to view as plaintext.

After failing over an instance in a cluster configuration, Git pushes to the instance will fail. This issue impacts pushes from the command line as well as the web interface. To resolve this issue, contact GitHub Support.

Restoring backups with ghe-restore on a GHES cluster will exit prematurely if redis has not restarted properly.

If a hotpatch upgrade requires the haproxy-frontend service to be restarted, the restart will hang if there are existing long-lived connections, such as browser web sockets or Git operations. No new connections will be accepted for up to 5 minutes. Any existing unfinished connections at this time will be disconnected. [Updated: 2024-06-17]

Upgrading GitHub Enterprise Server Backup Utilities using a Git repository is no longer supported

• The ability to upgrade the GitHub Enterprise Server Backup Utilities tool using a Git repository has been removed following changes to the github/backup-utils repository. For more information about the repository changes, see Repository updates - November 2023 in the project's README.

  Instead, to upgrade the tool using a compressed archive, download the relevant GitHub Enterprise Server Backup Utilities release from the Releases page of the github/backup-utils repository. For more information, see "Configuración de copias de seguridad en la instancia."

  This deprecation does not affect the functionality of the GitHub Enterprise Server Backup Utilities tool or your ability to backup or restore your GitHub Enterprise Server instance. [Updated: 2024-03-15]
