CI/CD security hardening (security/202610_updates)

Review-driven hardening of GitHub Actions CI and Dependabot. Only .github/ is touched.

Changes

Dependabot — .github/dependabot.yml (new)

  • Added Dependabot covering npm and github-actions, weekly.
  • Each ecosystem uses cooldown: { default-days: 7 } — only versions public for ≥7 days are proposed.

Workflow — ci.yml

  • Critical fix (token theft): the publish-npm job set NODE_AUTH_TOKEN at job level, so the npm token was present during npm ci / npm run build, where a malicious dependency install script could read it. NODE_AUTH_TOKEN is now scoped to the two npm publish steps only.
  • Added a tag ↔ package.json version check before publishing.
  • Added npm publish --provenance --access public.
  • Added top-level permissions: contents: read and job-level permissions: { contents: read, id-token: write } on publish-npm.

GitHub Actions — updated to latest

  • actions/checkout@v7, actions/setup-node@v7, actions/cache@v6.

Workflow — n8n.yml (new, copied in)

  • Added the shared "Trigger N8N Security Scan" workflow (previously absent here) in its hardened form: comment-triggered (/run-security-scan on a PR), gated to trusted commenters, payload built safely with jq, permissions: {}, and an Authorization: Bearer header.
  • Action required: create a repo secret N8N_BEARER_TOKEN; without it the step sends an empty bearer.

Checkout credential hardening — persist-credentials: false

  • actions/checkout writes the job's GITHUB_TOKEN into .git/config (as an http.extraheader) by default, where any later step can read it — including npm ci/npm install, whose dependency install scripts run arbitrary code. Scoping NODE_AUTH_TOKEN to the publish steps does not cover this separate Git credential.
  • Added persist-credentials: false to all 4 actions/checkout step(s) in this repo. None of these jobs perform authenticated Git operations after checkout, so nothing else is needed.
  • Note: cooldowns/persist-credentials only affect what's written to disk; the checkout itself still authenticates normally.

Review / testing notes

  • setup-node v→v7 changed NODE_AUTH_TOKEN handling — exercise a publish to confirm registry auth still works.
  • npm provenance requires package.json repository to match this repo + id-token: write (added) — validate on a test tag.
  • The version check assumes the git tag (vX.Y.Z, incl. any -next suffix) matches package.json version.

Summary by CodeRabbit

  • Chores
    • Weekly updates for npm packages and GitHub Actions are configured.
    • Releases verify that version tags match the package version and include provenance information.
  • New Features
    • Authorized contributors can trigger a security scan for a pull request by commenting /run-security-scan.

📝 Walkthrough

Walkthrough

The pull request configures weekly Dependabot updates, updates CI actions and npm publishing, and adds a workflow that sends qualifying pull request comments to an n8n webhook.

Changes

Dependency updates

Layer / File(s) Summary
Configure scheduled dependency updates
.github/dependabot.yml
Dependabot checks npm packages and GitHub Actions weekly in the Europe/Berlin timezone. Each ecosystem has a seven-day default cooldown.

CI and npm publishing

Layer / File(s) Summary
Update CI actions
.github/workflows/ci.yml
The lint, build, and test jobs use checkout v7, setup-node v7, and cache v6. The workflow grants contents: read permission.
Validate and publish releases
.github/workflows/ci.yml
The publish job checks that the version in a v tag matches package.json. It sets publishing permissions, scopes NODE_AUTH_TOKEN to publish steps, and requests npm provenance.

n8n security scan workflow

Layer / File(s) Summary
Trigger and send security scan payload
.github/workflows/n8n.yml
The workflow filters pull request comments by command and commenter association. It builds a JSON payload and posts it to the n8n webhook with a bearer token.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

1-19: LGTM!

92-99: Tag check matches the release-it tag format.

release-it sets tagName to v${version}. The check strips a leading v and compares the result with package.json. This matches, including -next suffixes. The --provenance and --access public options are valid for npm publish.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Set persist-credentials: false on checkout and disable the setup-node package-manager cache.

zizmor flags that actions/checkout persists the GITHUB_TOKEN in .git/config. In the publish job, later npm ci scripts can read it. Set persist-credentials: false. This is a low-effort hardening step that fits the aim of this PR.

zizmor also flags cache poisoning in the publish job. The release job restores no cache itself, but setup-node v7 may enable caching by default. Set package-manager-cache: false there so release artifacts cannot come from a poisoned cache.

Proposed fix for the publish job
-      - uses: actions/checkout@v7
-      - uses: actions/setup-node@v7
+      - uses: actions/checkout@v7
+        with:
+          persist-credentials: false
+      - uses: actions/setup-node@v7
         with:
           node-version: '22'
           registry-url: https://registry.npmjs.org/
+          package-manager-cache: false

official GitHub Actions documentation issue_comment github.ref github.sha event payload pull_request issue context

💡 Result:

For `issue_comment`, GitHub’s documented behavior is:

- It triggers for issue **or pull-request** comments (`created`, `edited`, or `deleted`). The workflow file must exist on the default branch. ([docs.github.com](https://docs.github.com/en/actions/reference/workflows-and-actions/events-that-trigger-workflows))
- `github.ref` / `GITHUB_REF` is the **default branch**, and `github.sha` / `GITHUB_SHA` is its **latest commit**—not the pull request’s head branch or commit. ([docs.github.com](https://docs.github.com/en/actions/reference/workflows-and-actions/events-that-trigger-workflows?ref=content.mainawycliffe.dev&utm_source=openai))
- The complete webhook payload is available as `github.event`. Since `issue_comment` covers both issues and PRs, check whether `github.event.issue.pull_request` exists to identify a PR comment. The docs establish that `github.event` is the full event payload; this property check follows the payload’s issue/PR distinction. ([docs.github.com](https://docs.github.com/en/actions/reference/workflows-and-actions/contexts?WT.mc_id=timheuer-blog-timheuer))
- For the PR’s head SHA, the `issue_comment` documentation does **not** define a dedicated `github.event.pull_request.head.sha` value. The documented `github.event.pull_request.head.sha` guidance applies to the `pull_request` event; don’t assume it is present in an `issue_comment` payload. ([docs.github.com](https://docs.github.com/en/actions/reference/workflows-and-actions/events-that-trigger-workflows?ref=content.mainawycliffe.dev))

```yaml
if: ${{ github.event.issue.pull_request }}
```

That condition limits a job to comments on pull requests, rather than ordinary issues.

Build the PR context from the issue_comment event.

For a reachable issue_comment trigger, github.event.pull_request is absent. The current payload therefore sends null for both PR identifiers and empty values for the PR refs and SHAs. github.ref_name and github.sha refer to the default branch for this event, so the scan can target the wrong commit.

Use github.event.issue.number, fetch repos/${REPO}/pulls/${PR}, and set the payload fields from the returned head and base objects. Grant the job pull-requests: read permission. Remove or separately source BEFORE, AFTER, and OVERRIDES, because issue_comment does not provide those fields.
