official actions/checkout persist-credentials default README

💡 Result:

The persist-credentials input for the official actions/checkout GitHub Action has a default value of true [1][2]. When set to true (the default), the action configures the authentication token or SSH key used to fetch the repository into the local git configuration [1][3][2]. This allows subsequent steps in your workflow to execute authenticated git commands (such as git fetch or git push) automatically [1][3]. The credentials are removed during the post-job cleanup [1][3]. In recent versions of actions/checkout, the implementation of this persistence has been improved for security; credentials are now stored in a separate file within $RUNNER_TEMP rather than directly in .git/config [1][4]. If you wish to prevent the action from persisting these credentials, you can explicitly set persist-credentials to false in your workflow configuration [1][3].

Sensitive Data Exposure

CWE: CWE-522 — Insufficiently Protected Credentials

Do not retain checkout credentials during the build.

The local action runs cargo in the checked-out external project. If its build scripts or dependencies run Git commands, persisted checkout credentials can authenticate those commands. Set persist-credentials: false on both checkout steps.

In @.github/workflows/test-build-options.yml at line 78, Update both
actions/checkout steps in the workflow to set persist-credentials to false,
ensuring credentials are not retained while the external project build runs.
Keep the existing checkout behavior otherwise unchanged.
