Summary
Pin all GitHub Actions workflow steps to immutable full commit SHAs instead of mutable tags or branches.
Why
Mutable tags can be moved after the fact, making it possible for a supply-chain attack to inject malicious code into CI. Pinning to a commit SHA ensures the exact version of an action is used, and the original tag is preserved as an inline comment for readability.
Verification
Review the diff — all
uses:lines with third-party actions should now reference a 40-character commit SHA with the original tag as an inline comment.🤖 Generated with Claude Code
