root - chore: defense - pin all GitHub Actions to full SHAs#139
Merged
Conversation
Pin every third-party GitHub Action to a full commit SHA (with a version
comment) instead of a floating major tag. Mutable tag/branch refs can be
moved to point at malicious commits; commit SHAs are immutable. This is a
supply-chain / defense-in-depth hardening change (no behavior change).
- actions/checkout v6 -> df4cb1c069e1874edd31b4311f1884172cec0e10 # v6.0.3
- actions/setup-node v6 -> 48b55a011bda9f5d6aeb4c2d9c7362e8dae4041e # v6.4.0
- codecov/codecov-action v7 -> fb8b3582c8e4def4969c97caa2f19720cb33a72f # v7.0.0
- github/codeql-action/{init,autobuild,analyze} v4 -> 8aad20d150bbac5944a9f9d289da16a4b0d87c1e # v4.36.2
pnpm/action-setup was already SHA-pinned (v6.0.8). All four workflow files
still parse.

Summary
Pin all third-party GitHub Actions to full commit SHAs (supply-chain / defense-in-depth hardening). No behavior change.
Why
Floating major tags (
@v6,@v7,@v4) are mutable — if an action's repo were compromised, the tag could be moved to point at a malicious commit. Pinning to immutable commit SHAs (each with a# vX.Y.Zcomment for readability) removes that risk.Pins
