Summary

  • CI node-version: 23 → 24. Node 23 is end of life and will not get the eMudhra CA fix.
  • Set check-latest: true. Without it, setup-node takes the first matching Node 24 from the runner's tool cache, which can still be a pre-24.22.1 build until the runner image refreshes.

Why

Eight eMudhra intermediate CA keys are compromised (advisory). Node.js does not use the OS trust store, it ships its own. The fix is in the Node.js October 21 security release (v26.12.1, v24.22.1 and v22.23.4), which also fixes three TLS hostname-check bypasses (CVE-2026-105483, CVE-2026-106069, CVE-2026-106072). Node 18 and 20 get no patch.

The floating node:* tags caught up with the release only this afternoon, so a cached base layer can still hold the vulnerable build. An exact pin rules that out.

Test plan

  • CI passes on Node 24

Node.js ships its own root store, which trusted the compromised eMudhra
intermediates until v26.12.1, v24.22.1 and v22.23.4. Pin a patched release.

P1 Badge Pin Node to the patched 24.22.1 release

On runners that already cache an older 24.x build, this major-only spec can still select the vulnerable build: setup-node@v4 defaults check-latest to false and checks its local cache for any matching semver before downloading (setup-node documentation). Since the security fixes first appear in 24.22.1 (Node.js advisory), this workflow does not guarantee the stated remediation on either ubuntu-latest or macos-latest; use the exact patched version (or enable check-latest).

Good catch, thanks. Added check-latest: true so setup-node downloads the patched Node 24 instead of using a stale cached build.

P1 Badge Pin the patched Node release

On either Ubuntu or macOS runners that still cache an older 24.x build, this does not guarantee the intended security fix: actions/setup-node@v4 treats 24 as a semver range, defaults check-latest to false, and uses the first locally cached match rather than downloading 24.22.1, as confirmed by the v4 documentation. Pin 24.22.1 (or enable check-latest) so these CI jobs cannot continue running a pre-fix Node 24 release.

setup-node resolves a major version from the runner's tool cache first,
which can still hold a pre-24.22.1 build until the runner image refreshes.
