About editing your configuration of default setup
After running an initial analysis of your code with default setup, you may need to make changes to your configuration to better meet your code security needs. For existing configurations of default setup, you can edit:
- Which languages default setup will analyze.
- The query suite run during analysis. For more information on the available query suites, see "CodeQL query suites."
If you need to change any other aspects of your code scanning configuration, consider configuring advanced setup. For more information, see "Configuring advanced setup for code scanning."
Customizing your existing configuration of default setup
-
On GitHub, navigate to the main page of the repository.
-
Under your repository name, click Settings. If you cannot see the "Settings" tab, select the dropdown menu, then click Settings.
-
In the "Security" section of the sidebar, click Code security and analysis.
-
In the "CodeQL analysis" row of the "Code scanning" section, select , then click View CodeQL configuration.

In the "CodeQL default configuration" window, click Edit.
-
Optionally, in the "Languages" section, select or deselect languages for analysis.
-
Optionally, in the "Query suite" row of the "Scan settings" section, select a different query suite to run against your code.
-
To update your configuration, as well as run an initial analysis of your code with the new configuration, click Save changes. All future analyses will use your new configuration.
Defining the alert severities that cause a check failure for a pull request
When you enable code scanning on pull requests, the check fails only if one or more alerts of severity error, or security severity critical or high are detected. The check will succeed if alerts with lower severities or security severities are detected. For important codebases, you may want the code scanning check to fail if any alerts are detected, so that the alert must be fixed or dismissed before the code change is merged. For more information about severity levels, see "About alert severity and security severity levels."
