Eight eMudhra (emSign) intermediate CAs had recoverable private keys, so anyone can mint a certificate for any domain that chains to roots Node still trusts. They were revoked on 2026-10-18, but Node does not check revocation and ships no fix: its built-in roots accept those chains on every current release. So the Docker image would accept a forged api.github.com or Ghost certificate, and send the Ghost Admin key to it.

The fix, in the runtime stage of the image:

• upgrade Alpine's ca-certificates-bundle to 20261020-r0, which removes the eight intermediates;
• run Node with NODE_OPTIONS=--use-openssl-ca, so it verifies against that system bundle instead of its own roots.

Version goes to 0.4.1; after merge the v0.4.1 tag runs the release. The npm package and the composite Action are not changed: they run on the caller's Node and the caller's CA store, which this repo does not control.

Summary by CodeRabbit

• Security

  • Updated the Docker runtime’s trusted certificate bundle to prevent trust in compromised eMudhra intermediate certificates.
  • Node-based applications in the Docker image now use the updated system certificate authorities.

• Release

  • Published version 0.4.1 with the certificate security update.
  • Users of the npm package or GitHub Action should ensure their Node.js runtime and system certificate bundle are up to date.

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 1b266

This release is meant to stop the Docker image from trusting compromised eMudhra intermediates. However, the build does not require the patched CA bundle version, so an image could ship still trusting them. Pin the minimum bundle version before merging. Also limit the release-note advice about --use-openssl-ca to platforms where it works, since following it on macOS can break HTTPS.

macOS mitigation or explicitly state that caller-controlled runtimes are not
fixed by this release, while preserving the Docker image guidance.

minimum version constraint of 20261020-r0 for ca-certificates-bundle, replacing
the unrestricted upgrade command.

⚠️ Action not completed

Review rate limited.

Note: CodeRabbit is an incremental review system and does not re-review already reviewed commits. This command is applicable only when automatic reviews are paused.

Both findings are fixed in 0533679: the Dockerfile requires ca-certificates-bundle>=20261020-r0, and the changelog says the npm package and the Action are unchanged. Re-review was rate limited.
