fix(ci): pin third-party actions to full commit SHAs

The account's Actions policy requires a full-length SHA ref. A tag or branch ref is refused at
startup — startup_failure, no jobs, "this workflow graph cannot be shown" — so these workflows
could not run at all. This resolves each ref to the commit it currently points at and records the
ref in a trailing comment, e.g. actions/checkout@<sha> # v4.

dtolnay/rust-toolchain takes its toolchain from the ref itself, so those steps also gained an
explicit with: toolchain: input; without it, a SHA ref would silently lose the channel.

No behaviour is intended to change beyond the pins.

Pin all reachable Node 20 actions to Node 24-compatible releases before 23 September 2026.

When GitHub-hosted runners remove Node 20, these JavaScript actions can fail to start. Replace each reference with a Node 24-compatible release, pin its commit SHA, and update the version comment. (github.blog)

official GitHub gh-actions-lock documentation --rescan actions.lock regenerate all workflows

💡 Result:

<search_synthesis>
The official GitHub tool for managing workflow dependency lockfiles is the gh CLI extension named gh-actions-lock [1]. To regenerate or update your lockfile using this tool, use the following commands: 1. To perform a standard update (which pins new actions or updates existing ones based on the current workflow definitions), run: gh actions-lock [1] 2. To specifically re-resolve references that have moved (such as updating branches or tags to their latest upstream commit SHAs), use the --relock flag: gh actions-lock --relock [1] If you encounter issues with "suspicious" pins where the recorded commit is no longer reachable, you can add the --accept-moved flag to force re-resolution [1]. Note: There is a separate, third-party tool called gh-actions-lockfile (often found at gjtorikian/gh-actions-lockfile) which is not certified by GitHub [2][3]. Users of that tool typically use the command gh-actions-lockfile generate to update their lockfiles [2][4]. Ensure you are using the correct tool for your repository&#39;s configuration [1][3].

<title>github/gh-actions-lock</title> https://github.com/github/gh-actions-lock # github/gh-actions-lock A gh CLI extension that generates and verifies the GitHub Actions dependency lockfile, pinning every action your workflows use to an exact commit. - Stars: 21 - Forks: 2 - Watchers: 21 - Open issues: 3 - License: MIT License - Default branch: main - Created: 2026-04-22T04:45:53Z ## Languages - Go - Makefile - Ruby - Shell ## Topics - cli - dependency-pinning - gh-extension - github-actions - go - lockfile - security - supply-chain-security ## Top Contributors - nodeselector (30 contributions) - Steve-Glass (1 contributions) --- ## README # gh-actions-lock Lock your workflow dependencies. > [!WARNING] > **Technical Preview.** gh-actions-lock is pre-1.0 and under active development. The > lockfile format, command flags, and behavior may change without notice between > releases. Use it, file issues, and expect rough edges. ## Background gh-actions-lock is part of GitHub&`#39`;s Workflow Dependency Pinning effort. It gives repositories a lockfile that pins every workflow dependency to a verified commit, so what runs on the runner is exactly what you locked. Development is ongoing and behavior may still change. Contributions are welcome. See CONTRIBUTING.md to get started. ## Requirements Requires the `gh` CLI. Install it first, then install the extension: ```bash gh extension install github/gh-actions-lock ``` ## Usage Scan every workflow under `.github/workflows/` directory, pin each resolvable action to a SHA, and update the lockfile: ```bash gh actions-lock ``` After the initial run to onboard workflows, you will need to run `gh actions-lock` when: - A new workflow is created that has `uses` dependencies. - An existing workflow adds or removes `uses` dependencies. A full-directory run (`gh actions-lock` with no path arguments) also prunes lockfile entries for workflows that have been deleted from `.github/workflows/`, dropping any dependencies left orphaned by the removal. Scoped runs that name specific workflows never prune out-of-scope entries. Pins to branches or partial versions (e.g. `main`, `v4`) are trusted from the lockfile and not re-resolved on a normal run. To bump them to the current upstream commit, run: ```bash gh actions-lock --relock ``` `--relock` re-resolves refs that have legitimately moved and rewrites the lockfile to the new SHA. Suspicious pins whose recorded commit is no longer reachable upstream are left as errors — use `--accept-moved` to re-resolve those as well. ### Self repository actions (`$/…`) `uses: $/…` references an action or reusable workflow in the **same repository** as the defining file, resolved at the **running commit**. Because it always resolves to that repository&amp;`#39`;s running SHA it is **inherently pinned** — no lockfile entry is required, and it is valid anywhere a relative `./…` reference is: ```yaml steps: - uses: $/actions/my-action # same-repo action, inherently pinned jobs: call: uses: $/.github/workflows/reusable.yml # same-repo reusable workflow ``` A trailing `@ref` (e.g. `$/actions/my-action@v1`) is rejected — the ref is always the running commit. Same-repo `./…` composite action references are automatically converted to `$/…` on fix runs. This rewrites `./…` steps both in your workflows and in your in-repo composite action definitions (`action.yml`). Only `./…` paths that resolve to an in-repo action file are rewritten. To leave `./…` refs untouched, opt out with `--no-migrate-local-actions`: ```bash gh actions-lock --no-migrate-local-actions ``` ## How it works A repo gets a lockfile (located at `.github/workflows/actions.lock`) and workflows are onboarded to the lockfile on a per-workflow basis. Workflows that are onboarded to the lockfile enforce that all dependencies are present in the lockfile and guarantees that the locked commit for an Action is what&`#39`;s executed on the runner. Lockfiles are also verified for forgeries. The sha must exist in the refs it&`#39`;s stated to exist in.

This creates several security and reliability concerns: - Mutable version tags: Version tags like`@v4` can be silently retagged to point to different code - Hidden dependencies: Composite actions pull in transitive dependencies you can’t see or audit - No integrity verification: There’s no built-in way to verify that the action code hasn’t changed For more background, see “ GitHub Actions Has a Package Manager, and It Might Be the Worst”. ## Quick Start ### Option 1: As a GitHub Action (recommended) Add verification to your CI workflow: ``` - uses: gjtorikian/gh-actions-lockfile@v1 with: mode: verify # or &`#39`;generate&`#39`; ``` #### Permissions for PR Comments When using`verify` mode with the`comment: true` option (default), the action posts a comment on pull requests if verification fails. This requires write permissions: ``` permissions: pull-requests: write jobs: verify: runs-on: ubuntu-latest steps: - uses: actions/checkout@v6 - uses: gjtorikian/gh-actions-lockfile@v1 with: mode: verify ``` Without these permissions, you’ll see:`Resource not accessible by integration`. ### Option 2: Via the CLI Install globally via npm: ``` npm install -g gh-actions-lockfile ``` Then run: ``` # Generate a lockfile from your workflows gh-actions-lockfile generate # Verify workflows match the lockfile (exits 1 on mismatch) gh-actions-lockfile verify # Show dependency tree gh-actions-lockfile list ``` Or use`npx` without installing: ``` npx gh-actions-lockfile generate ``` ## What’s in the Lockfile? The lockfile pins each action to: - SHA: The exact Git commit hash - Integrity: A SHA-256 hash of the action’s content - Dependencies: Any transitive dependencies from composite actions ``` { "version": 1, "generated": "2025-12-15T20:37:39.422Z", "actions": { "actions/checkout": [ { "version": "v4", // This is the Git commit SHA (the 40-character hex hash). // It identifies the exact commit in the action&`#39`;s repository that will be checked out. // It answers: "which version of the code should I fetch?" "sha": "11bd71901bbe5b1630ceea73d27597364c9af683", // This is a Subresource Integrity (SRI) hash of the action&`#39`;s content (using SHA-256). // It answers: "is the content I fetched what I expected?" "integrity": "sha256-abc123...", // This tracks transitive dependencies — other GitHub Actions that a composite action uses internally. "dependencies": [] } ] } } ``` ## Next Steps - Usage- Learn the recommended workflow for generating and verifying lockfiles - Commands- Explore all available commands - CLI Reference- See all CLI options and environment variables <title>CLI Reference | gh-actions-lockfile</title> https://gh-actions-lockfile.net/docs/cli-reference/ CLI Reference | gh-actions-lockfile # CLI Reference Complete reference for all CLI options and environment variables. Authentication Recommended When running locally, set a `GITHUB_TOKEN` environment variable to avoid rate limits. Without it, you&`#39`;re limited to 60 API requests per hour. ``` export GITHUB_TOKEN=ghp_your_token_here ``` ## Options All commands accept the following options: ### `-w, --workflows ` Path to the workflows directory. Default: `.github/workflows` ``` node dist/cli.js generate --workflows ./my-workflows ``` ### `-o, --output ` Path to the lockfile. Default: `.github/actions.lock.json` ``` node dist/cli.js generate --output ./lockfile.json ``` ### `-t, --token ` GitHub token for API authentication. Required for private repositories or to avoid rate limiting. ``` node dist/cli.js generate --token ghp_xxxxxxxxxxxx ``` ### `--require-sha` Require all action references to be full 40-character commit SHAs. Fails if any workflow uses tags like `@v4` instead of full SHAs. ``` node dist/cli.js generate --require-sha ``` ### `--skip-sha` Skip SHA resolution verification. This makes verification faster but less secure. ``` node dist/cli.js verify --skip-sha ``` ### `--skip-integrity` Skip integrity hash verification. This makes verification faster but less secure. ``` node dist/cli.js verify --skip-integrity ``` ### `--skip-advisories` Skip checking locked actions against the GitHub Advisory Database for known vulnerabilities. Advisory checking is enabled by default. ``` # Disable advisory checking node dist/cli.js verify --skip-advisories ``` ### `-c, --comment` / `--no-comment` Post a PR comment when verification fails. Enabled by default. ``` # Disable PR comments node dist/cli.js verify --no-comment ``` ### `GITHUB_TOKEN` Alternative to the `--token` option. If both are provided, the command-line option takes precedence. ``` export GITHUB_TOKEN=ghp_xxxxxxxxxxxx node dist/cli.js generate ``` In GitHub Actions, this is automatically available: ``` - uses: gjtorikian/gh-actions-lockfile@v1 with: mode: generate env: GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} ``` ### Node.js (Recommended) The built CLI works with Node.js without additional dependencies: ``` node dist/cli.js <command> [options] ``` ### Development Mode You can also run directly from source with tsx: ``` npx tsx src/index.ts <command> [options] ``` ## Examples Generate a lockfile with custom paths: ``` node dist/cli.js generate \ --workflows ./workflows \ --output ./workflows/actions.lock.json ``` Verify in CI with explicit token: ``` GITHUB_TOKEN=${{ secrets.GITHUB_TOKEN }} node dist/cli.js verify ``` List dependencies for a specific lockfile: ``` node dist/cli.js list --output ./custom-lockfile.json ``` gh-actions-lockfile is open source under the AGPL-3.0 license.

Regenerate the actions lockfile with --relock.

.github/workflows/actions.lock records hyperpolymath/cicd-suite@main at fc64172aa53e85289d5d7d6e15c2435a867cc1c9, but this workflow pins commit 180b419825d238f8b606584c970a81dfa7cb6f81. Run gh actions-lock --relock without a workflow path so it rescans .github/workflows/ and updates both workflow entries. Do not edit the generated file manually.
