chore: enforce PR type labels and independent review (SOC2) - #11

Priority: ⚪ Not assessed Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟠 High · up to The new required type-label check can be redefined by the same pull request it evaluates, allowing the repository’s intended merge control to be bypassed.

GitHub Actions pull_request workflow file merge commit pull_request_target base branch workflow security official documentation
💡 Result:
In GitHub Actions, the pull_request and pull_request_target event triggers differ fundamentally in their security posture and context [1][2][3]. Key Differences and Security Implications pull_request - Context: Runs the workflow file from the merge commit of the pull request [1][2]. - Security: Considered unprivileged and safe for untrusted code [1][4]. GitHub automatically restricts these workflows by providing a read-only GITHUB_TOKEN, withholding access to repository secrets, and preventing access to privileged caches [1][3]. - Best Practice: Use this for building and testing code from pull requests [2][3]. pull_request_target - Context: Runs the workflow file from the base repository's default branch [1][2]. - Security: Considered a privileged context [5][4]. Because it runs using trusted code from your default branch, it is granted access to repository secrets and read/write permissions for the GITHUB_TOKEN [1][6][3]. - Risk: If you use actions/checkout to fetch the head of an untrusted pull request within a pull_request_target workflow, you may unintentionally execute malicious code with your repository's full privileges—a vulnerability known as a "pwn request" [5][7]. Recent Security Enhancements As of June 2026, actions/checkout (version 7 and later) includes built-in protection for pull_request_target workflows [7]. It will refuse to check out the head of a pull request from a fork unless you explicitly opt out by setting allow-unsafe-pr-checkout: true [1][7]. This flag is intentionally named to be highly visible during code reviews [1][7]. Recommended Secure Workflow Pattern To perform operations that require both untrusted pull request data and elevated permissions (such as posting comments or labeling), follow this two-stage approach: 1. Unprivileged Workflow: Triggered by pull_request. This workflow processes the untrusted code, runs tests, and saves the results as artifacts [4][8]. 2. Privileged Workflow: Triggered by workflow_run. This workflow waits for the first workflow to complete, then downloads the verified artifacts and performs the necessary privileged actions (using repository secrets or write permissions) [5][4][8]. This pattern ensures that untrusted code is never executed in an environment that has access to secrets or write tokens [4][8].

Authorization Bypass (CWE-862): Missing Authorization

Run the required check from trusted workflow code.
pull_request loads this workflow from the pull request's merge commit. A pull request can change the validation logic while preserving the required pr-type-label job. Use pull_request_target unless changes to this workflow are separately protected.
Keep the current no-checkout design, least-privilege permissions, and no execution of pull-request code.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
