In @.github/workflows/triage_prs.yml:
- Around line 6-9: The workflow grants unnecessary broad permission via the
permissions block—specifically the issues: write entry; remove or reduce that
scope to least privilege by deleting the issues: write line (or set issues:
none) while keeping only the needed permissions (e.g., pull-requests: read and
contents: read) so the permissions block contains no higher-than-required
rights.
- Around line 19-20: The grep used to check PR_AUTHOR currently allows regex
interpretation and is case-sensitive; update the check that references PR_AUTHOR
so it uses fixed-string and case-insensitive matching (add grep flags -F and -i,
and keep -x and -q for exact/quiet match) to avoid false negatives for usernames
like dependabot[bot]; modify the conditional that calls grep for " -
$PR_AUTHOR" accordingly so it uses fixed-string, case-insensitive matching.
- Line 15: The workflow is using the mutable ref actions/add-to-project@main
which weakens supply-chain integrity; update the GitHub Actions step that
references actions/add-to-project@main to pin it to the specific commit SHA
244f685bbc3b7adfa8466e08b698b5577571133e (i.e., use
actions/add-to-project@244f685bbc3b7adfa8466e08b698b5577571133e) so the action
is immutable and reproducible while leaving actions/checkout@v6 unchanged.
- Around line 2-4: Change the workflow trigger from pull_request to
pull_request_target so the job runs in the base-repo context and can access
repository secrets (e.g., secrets.ADD_TO_PROJECT_PAT) for forked PRs; update the
on: block (the existing pull_request types: [opened] entry and the other
pull_request uses at lines referenced) to use pull_request_target with the same
types array (e.g., types: [opened]) and verify any workflow steps that assume
head repo checkout still use actions/checkout with ref and persist-credentials:
false or use a separate checkout for the forked PR content to maintain security.

actions/add-to-project GitHub Action mutable refs immutable security
💡 Result:
- In
uses: actions/add-to-project@…, the part after@is a git ref (branch, tag, or commit SHA). Branches and tags are mutable pointers (they can be force-moved), so a workflow pinned to@mainor even@v1.0.2can be changed to run different code later if that ref is moved. GitHub’s security guidance is to pin third-party actions to a full-length commit SHA to make the dependency immutable. [1] - For
actions/add-to-project, the most recent release shown is v1.0.2 (Jun 24, 2024), which points at commit244f685bbc3b7adfa8466e08b698b5577571133e. To make the reference immutable, use:uses: actions/add-to-project@244f685bbc3b7adfa8466e08b698b5577571133e(optionally add a comment like# v1.0.2). [2]
- If you maintain an action, GitHub also documents “immutable releases and tags” patterns—but note that git tags themselves can still be moved, so consumers who need immutability should still pin by SHA. [3]
- At the platform/governance level, GitHub added policy controls that support enforcing SHA pinning / blocking unpinned actions, to reduce supply-chain risk from compromised or retagged actions. [4]

Pin actions/add-to-project to a full commit SHA for supply-chain integrity.
actions/add-to-project@main is mutable and weakens supply-chain integrity. The latest release is v1.0.2 (June 24, 2024), which points to 244f685bbc3b7adfa8466e08b698b5577571133e. Pin it to the full commit SHA instead of using the @main branch.
🔧 Proposed fix
- uses: actions/add-to-project@main
+ uses: actions/add-to-project@244f685bbc3b7adfa8466e08b698b5577571133eNote: actions/checkout@v6 is a valid published ref and does not require changes.

I'm not sure we should be terribly worried about this. We do the same in triage_issues.yml:
There was a problem hiding this comment.
@mathesoncalum, that's a fair point — consistency with the existing triage_issues.yml is a reasonable justification, and the risk is low given that actions/add-to-project is a first-party GitHub action maintained by the GitHub org itself. I'll note this for future reviews.

Learning: In the musescore/MuseScore repository, the workflow files under `.github/workflows/` intentionally use `actions/add-to-projectmain` (mutable ref) rather than pinning to a full commit SHA. This is a deliberate, consistent pattern established in `triage_issues.yml` and `triage_prs.yml`. Do not flag this as a supply-chain security issue in future reviews for this repository.
