Pin shivammathur/setup-php to commit SHA for supply chain safety - #34
Merged
Conversation
All other third-party GitHub Actions in the repository workflows are pinned to immutable commit SHAs. The PHP workflow was the only one still referencing a mutable tag (v2), which exposes the CI runner (and the PROXY_URL secret) to a tag-repointing supply chain attack. Pin to the current v2 commit SHA (b604ade2) to match the repository's existing pinning convention. Co-authored-by: ProxyMesh AI <proxymeshai@users.noreply.github.com>
