🔴 HIGH RISK
This workflow block presents two significant security issues:
ahmadnassri/action-dependabot-auto-merge@v2(line 14) is still using a mutable version tag, which contradicts the security goals of this PR. It should be updated to a specific commit SHA.pull_request_targetwhile checking out the pull request's head branch (lines 11-13) is a high-severity vulnerability. It allows potentially untrusted code from a fork to run with write permissions and access to repository secrets.Actionable Suggestions:
Find the latest commit SHA for ahmadnassri/action-dependabot-auto-merge@v2 and update the uses statement in .github/workflows/auto-merge.yml to use that SHA, including the version as a comment (e.g., # v2).actions/checkoutis necessary. If the action only needsGITHUB_TOKENfor API calls, remove the checkout step and therefparameter to eliminate the risk of executing untrusted code.
