Pin GitHub Actions to commit SHAs
GitHub Actions referenced by tag (e.g.
actions/checkout@v4) use a mutable pointer — the tag owner can move it to a different commit at any time, including a malicious one. This is the attack vector used in the tj-actions/changed-files incident (CVE-2025-30066).Pinning to a full 40-character commit SHA makes the reference immutable. The
# tagcomment preserves human readability so reviewers can tell which version is pinned.Important: a SHA can also originate from a forked repository. A malicious actor can fork an action, push a compromised commit to the fork, and the SHA will resolve — but it won't exist in the upstream canonical repo. Each SHA in this PR was verified against the action's canonical repository (not a fork).
