Summary
Pin all GitHub Action references to full commit SHAs instead of mutable version tags to prevent supply chain attacks. This is a security best practice recommended by GitHub's security hardening guide.
Mutable version tags (e.g.
@v2) can be moved to point to different commits, meaning a compromised upstream action could execute malicious code in our workflows. Pinning to commit SHAs ensures we always run the exact code we've reviewed.Related: apm-telegen-3022
