Pin every `uses:` ref in .github/workflows and composite actions to a
full 40-character commit SHA, with the original tag preserved as a
comment, e.g.
uses: actions/checkout@11bd719 # v4
Tags and branches are mutable; commit SHAs are not. Pinning to a SHA
closes a supply-chain vector where a compromised action could replace
what runs in CI without changing the tag we reference.
Generated mechanically with `pinact run`
(https://github.com/suzuki-shunsuke/pinact). No version bumps were
applied (strict pin).

Summary
Pin every
uses:ref in.github/workflows/(and any composite actionfiles) to a full 40-character commit SHA, with the original tag
preserved as a
# vXcomment.Why
Tags and branches are mutable, so a compromised action can replace what
runs in our pipelines without changing the tag we reference. Pinning to
a SHA closes that supply-chain vector. See GitHub's hardening guide:
https://docs.github.com/en/actions/security-guides/security-hardening-for-github-actions#using-third-party-actions.
Deadline
TechOps is enforcing SHA-pinned GitHub Actions across the org by
June 8, 2026. Merging this PR brings the repo into compliance ahead
of the cut-over; after that date workflows that still reference
mutable tags or branches will be blocked from running.
How
Generated mechanically with
pinact run.No version bumps were applied (strict pin); follow-up upgrades can come
from Renovate or a separate
pinact run -uPR.Test plan
Note
Low Risk
Low risk: workflow-only changes that swap mutable action tags for pinned commit SHAs, with no application/runtime logic changes. Main risk is CI breakage if any pinned SHAs are incorrect or removed upstream.
Overview
Hardens CI supply chain by replacing mutable
uses: ...@vXreferences with full 40-character commit SHAs (keeping the original version as a comment) across theCIandCodeQLworkflows.This pins
actions/checkout,actions/setup-node, Docker build/push/login/setup actions, andgithub/codeql-actionsteps (including SARIF upload) to specific commits without changing the workflow behavior otherwise.Reviewed by Cursor Bugbot for commit bbb7061.
