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 reference pinning with no step logic changes; behavior should match prior tagged versions at the pinned commits.
Overview
Pins every
uses:reference touched in CI workflows from mutable tags (@v1,@v4, etc.) to immutable 40-character commit SHAs, keeping the original version in a trailing# vXcomment for readability.Coverage spans build/lint/test, main (merge queue, workflow lint, release detection), create-release-pr, publish-release (artifacts + npm), publish-registry (checkout, deploy, cross-repo dispatch), and security-code-scanner. MetaMask composite actions (
action-checkout-and-setup,action-npm-publish,github-toolshelpers, etc.) and common third-party steps (actions/checkout,upload-artifact,download-artifact,github-script) are included; no functional workflow logic or inputs change—only how action versions are resolved at runtime.This aligns the repo with org supply-chain hardening (tags can be retargeted; SHAs cannot).
