Summary
Pins all third-party GitHub Actions across
.github/workflows/and thesetup-workspacecomposite action to immutable commit SHAs (with version comments) using pinact, reducing supply-chain risk from tag-retargeting attacks.Why
Action version tags (
@v4) are mutable — a compromised maintainer or token could retarget a tag to malicious code that runs in CI with our secrets. Pinning to a SHA makes the executed code immutable while the trailing# vX.Y.Zcomment preserves readability and dependency-update tooling support.Changes
