Conversation
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.
Merging this PR brings the repo into compliance; workflows that still
reference mutable tags or branches may 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
Workflow-only supply-chain hardening with no application or runtime behavior changes; CI should behave the same as before at the pinned commits.
Overview
Replaces mutable
uses:tags (e.g.@v3,@v1) with full commit SHAs acrossbuild-lint-test.yml,create-release-pr.yml, andpublish-release.yml, keeping the original version in# vXcomments for readability.Affected actions include
actions/checkout,actions/setup-node,actions/cache, and MetaMask release helpers (action-create-release-pr,action-is-release,action-publish-release,action-npm-publish). Job steps, matrices, and permissions are unchanged—only how those actions are referenced.Reviewed by Cursor Bugbot for commit 6f56703. Bugbot is set up for automated code reviews on this repo.
