Summary
Pin all third-party GitHub Actions to full-length commit SHAs to prevent supply chain attacks.
Addresses findings from the
third-party-action-not-pinned-to-commit-shaSemgrep rule.Test plan
Note
Low Risk
Low risk: workflow-only changes that pin action versions; main risk is CI/release breakage if a pinned SHA is incorrect or later removed.
Overview
Pins third-party GitHub Actions in
manual-publish.ymlandrelease-please.ymlto specific commit SHAs (with version comments) instead of floating tags.This includes pinning
pypa/gh-action-pypi-publish, the SLSA provenance generator workflow, andgoogleapis/release-please-action, reducing supply-chain risk for release/publish pipelines.Written by Cursor Bugbot for commit ecba454. This will update automatically on new commits. Configure here.
