Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation through the NameChain DNS verification logic in src/rust/cryptography-x509-verification. An attacker can make a peer name, such as bar.example.com, validate against a wildcard leaf certificate like...

cryptography has incomplete DNS name constraint enforcement on peer names

Summary In versions of cryptography prior to 46.0.5, DNS name constraints were only validated against SANs within child certificates, and not the "peer name" presented during each validation. Consequently, cryptography would allow a peer named bar.example.com to validate against a wildcard leaf...

Improper Certificate Validation

Overview org.webjars.npm:node-forge is a WebJar for node-forge. Affected versions of this package are vulnerable to Improper Certificate Validation in the verifyCertificateChain function. An attacker can gain unauthorized certificate authority capabilities by presenting a certificate chain where ...

GHSA-2328-F5F3-GJ25 Forge has a basicConstraints bypass in its certificate chain verification (RFC 5280 violation)

Summary pki.verifyCertificateChain does not enforce RFC 5280 basicConstraints requirements when an intermediate certificate lacks both the basicConstraints and keyUsage extensions. This allows any leaf certificate without these extensions to act as a CA and sign other certificates, which node-for...
