Affichage et mise à jour des alertes Dependabot

Your repository's Dependabot alerts tab lists all open and closed Dependabot alerts and corresponding Dependabot security updates. You can filter alerts by package, ecosystem, or manifest. You can sort the list of alerts, and you can click into specific alerts for more details. You can also dismiss or reopen alerts, either one by one or by selecting multiple alerts at once. For more information, see "About Dependabot alerts."

You can enable automatic security updates for any repository that uses Dependabot alerts and the dependency graph. For more information, see "About Dependabot security updates."

About updates for vulnerable dependencies in your repository

GitHub generates Dependabot alerts when we detect that the default branch of your codebase is using dependencies with known security risks. For repositories where Dependabot security updates are enabled, when GitHub detects a vulnerable dependency in the default branch, Dependabot creates a pull request to fix it. The pull request will upgrade the dependency to the minimum possible secure version needed to avoid the vulnerability.

Dependabot doesn't generate Dependabot alerts for malware. For more information, see "About the GitHub Advisory database."

Each Dependabot alert has a unique numeric identifier and the Dependabot alerts tab lists an alert for every detected vulnerability. Legacy Dependabot alerts grouped vulnerabilities by dependency and generated a single alert per dependency. If you navigate to a legacy Dependabot alert, you will be redirected to a Dependabot alerts tab filtered for that package.

You can filter and sort Dependabot alerts using a variety of filters and sort options available on the user interface. For more information, see "Prioritizing Dependabot alerts" below.

You can also audit actions taken in response to Dependabot alerts. For more information, see "Auditing security alerts."

Prioritizing Dependabot alerts

GitHub helps you prioritize fixing Dependabot alerts. By default, Dependabot alerts are sorted by importance. The "Most important" sort order helps you prioritize which Dependabot alerts to focus on first. Alerts are ranked based on their potential impact, actionability, and relevance. Our prioritization calculation is constantly being improved and includes factors like CVSS score, dependency scope, and whether vulnerable function calls are found for the alert.

You can also use Dependabot auto-triage rules to prioritize Dependabot alerts. For more information, see “About Dependabot auto-triage rules.”

You can sort and filter Dependabot alerts by typing filters as key:value pairs into the search bar.

Option	Description	Example
ecosystem	Displays alerts for the selected ecosystem	Use ecosystem:npm to show Dependabot alerts for npm
has	Displays alerts meeting the selected filter criteria	Use has:patch to show alerts related to advisories that have a patch Use has:vulnerable-calls to show alerts relating to calls to vulnerable functions
is	Displays alerts based on their state	Use is:open to show open alerts
manifest	Displays alerts for the selected manifest	Use manifest:webwolf/pom.xml to show alerts on the pom.xml file of the webwolf application
package	Displays alerts for the selected package	Use package:django to show alerts for django
resolution	Displays alerts of the selected resolution status	Use resolution:no-bandwidth to show alerts previously parked due to lack of resources or time to fix them
repo	Displays alerts based on the repository they relate to Note that this filter is only available for security overview. For more information, see "About security overview"	Use repo:octocat-repo to show alerts in the repository called octocat-repo
scope	Displays alerts based on the scope of the dependency they relate to	Use scope:development to show alerts for dependencies that are only used during development
severity	Displays alerts based on their level of severity	Use severity:high to show alerts with a severity of High
sort	Displays alerts according to the selected sort order	The default sorting option for alerts is sort:most-important, which ranks alerts by importance Use sort:newest to show the latest alerts reported by Dependabot

In addition to the filters available via the search bar, you can sort and filter Dependabot alerts using the dropdown menus at the top of the alert list. Alternatively, to filter by label, click a label assigned to an alert to automatically apply that filter to the alert list.

The search bar also allows for full text searching of alerts and related security advisories. You can search for part of a security advisory name or description to return the alerts in your repository that relate to that security advisory. For example, searching for yaml.load() API could execute arbitrary code will return Dependabot alerts linked to "PyYAML insecurely deserializes YAML strings leading to arbitrary code execution" as the search string appears in the advisory description.

Alerts for packages listed as development dependencies are marked with the Development label on the Dependabot alerts page and are also available for filtering via the scope filter.

The alert details page of alerts on development-scoped packages shows a "Tags" section containing a Development label.

About the detection of calls to vulnerable functions

When Dependabot tells you that your repository uses a vulnerable dependency, you need to determine what the vulnerable functions are and check whether you are using them. Once you have this information, then you can determine how urgently you need to upgrade to a secure version of the dependency.

For supported languages, Dependabot automatically detects whether you use a vulnerable function and adds the label "Vulnerable call" to affected alerts. You can use this information in the Dependabot alerts view to triage and prioritize remediation work more effectively.

You can filter the view to show only alerts where Dependabot detected at least one call to a vulnerable function using the has:vulnerable-calls filter in the search field.

For alerts where vulnerable calls are detected, the alert details page shows additional information:

• One or more code blocks showing where the function is used.
• An annotation listing the function itself, with a link to the line where the function is called.

For more information, see "Reviewing and fixing alerts" below.

Viewing Dependabot alerts

You can view all open and closed Dependabot alerts and corresponding Dependabot security updates in your repository's Dependabot alerts tab. You can sort and filter Dependabot alerts by selecting a filter from the dropdown menu.

1. On GitHub, navigate to the main page of the repository.

2. Under the repository name, click Security. If you cannot see the "Security" tab, select the dropdown menu, and then click Security.

   

3. In the "Vulnerability alerts" sidebar of security overview, click Dependabot. If this option is missing, it means you don't have access to security alerts and need to be given access. For more information, see "Managing security and analysis settings for your repository."

   

4. Optionally, to filter alerts, select a filter in a dropdown menu then click the filter that you would like to apply. You can also type filters into the search bar. Alternatively, to filter by label, click a label assigned to an alert to automatically apply that filter to the alert list. For more information about filtering and sorting alerts, see "Prioritizing Dependabot alerts."

   

5. Click the alert that you would like to view.

6. Optionally, to suggest an improvement to the related security advisory, on the right-hand side of the alert details page, click Suggest improvements for this advisory on the GitHub Advisory Database. For more information, see "Editing security advisories in the GitHub Advisory Database."

   

Reviewing and fixing alerts

It’s important to ensure that all of your dependencies are clean of any security weaknesses. When Dependabot discovers vulnerabilities in your dependencies, you should assess your project’s level of exposure and determine what remediation steps to take to secure your application.

If a patched version of the dependency is available, you can generate a Dependabot pull request to update this dependency directly from a Dependabot alert. If you have Dependabot security updates enabled, the pull request may be linked in the Dependabot alert.

In cases where a patched version is not available, or you can’t update to the secure version, Dependabot shares additional information to help you determine next steps. When you click through to view a Dependabot alert, you can see the full details of the security advisory for the dependency including the affected functions. You can then check whether your code calls the impacted functions. This information can help you further assess your risk level, and determine workarounds or if you’re able to accept the risk represented by the security advisory.

For supported languages, Dependabot detects calls to vulnerable functions for you. When you view an alert labeled as "Vulnerable call", the details include the name of the function and a link to the code that calls it. Often you will be able to take decisions based on this information, without exploring further.

Fixing vulnerable dependencies

1. View the details for an alert. For more information, see "Viewing Dependabot alerts" (above).

2. If you have Dependabot security updates enabled, there may be a link to a pull request that will fix the dependency. Alternatively, you can click Create Dependabot security update at the top of the alert details page to create a pull request.

   

3. Optionally, if you do not use Dependabot security updates, you can use the information on the page to decide which version of the dependency to upgrade to and create a pull request to update the dependency to a secure version.

4. When you're ready to update your dependency and resolve the vulnerability, merge the pull request.

   Each pull request raised by Dependabot includes information on commands you can use to control Dependabot. For more information, see "Managing pull requests for dependency updates."

Dismissing Dependabot alerts

If you schedule extensive work to upgrade a dependency, or decide that an alert does not need to be fixed, you can dismiss the alert. Dismissing alerts that you have already assessed makes it easier to triage new alerts as they appear.

1. View the details for an alert. For more information, see "Viewing vulnerable dependencies" (above).

2. Select the "Dismiss" dropdown, and click a reason for dismissing the alert. Unfixed dismissed alerts can be reopened later.

3. Optionally, add a dismissal comment. The dismissal comment will be added to the alert timeline and can be used as justification during auditing and reporting. You can retrieve or set a comment by using the GraphQL API. The comment is contained in the dismissComment field. For more information, see "Objects" in the GraphQL API documentation.

   

4. Click Dismiss alert.

Dismissing multiple alerts at once

1. View the open Dependabot alerts. For more information, see "Viewing and updating Dependabot alerts".
2. Optionally, filter the list of alerts by selecting a dropdown menu, then clicking the filter that you would like to apply. You can also type filters into the search bar.
3. To the left of each alert title, select the alerts that you want to dismiss.
   
4. Optionally, at the top of the list of alerts, select all alerts on the page.
   
5. Select the "Dismiss alerts" dropdown, and click a reason for dismissing the alerts.
   

Viewing and updating closed alerts

You can view all open alerts, and you can reopen alerts that have been previously dismissed. Closed alerts that have already been fixed cannot be reopened.

1. On GitHub, navigate to the main page of the repository.

2. Under the repository name, click Security. If you cannot see the "Security" tab, select the dropdown menu, and then click Security.

   

3. In the "Vulnerability alerts" sidebar of security overview, click Dependabot. If this option is missing, it means you don't have access to security alerts and need to be given access. For more information, see "Managing security and analysis settings for your repository."

   

4. To just view closed alerts, click Closed.

   

5. Click the alert that you would like to view or update.

6. Optionally, if the alert was dismissed and you wish to reopen it, click Reopen. Alerts that have already been fixed cannot be reopened.

   

Reopening multiple alerts at once

1. View the closed Dependabot alerts. For more information, see "Viewing and updating Dependabot alerts" (above).
