  "title": "X.509 name-constraints validation bypass in node-forge",
  "summary": "node-forge certificate-chain validation through version 1.4.2 does not enforce non-critical X.509 name constraints. An attacker with access to a certificate or private key from an affected constrained CA may have certificates accepted for names outside that CA's authorized scope. Applications are affected when they validate chains with node-forge and trust a hierarchy containing such a CA.",
  "mitigation": "Upgrade node-forge to version 1.4.3 or later. Until upgraded, reject chains containing CA certificates with a name-constraints extension in the certificate verification callback, and review trust anchors separately.",
