  "title": "Certificate-chain validation bypass in node-forge",
  "summary": "Applications using node-forge certificate-chain or TLS peer validation can accept a certificate as a certificate authority when it should not be treated as one. An attacker needs a certificate issued by an application-trusted CA that preserves a crafted deprecated extension; this can permit certificates for arbitrary names to be accepted.",
  "mitigation": "Upgrade node-forge to version 1.4.1 or later. Until upgraded, reject chains unless each non-leaf certificate has the standard basic-constraints extension and it explicitly permits CA use.",
