Chain intermediate CA:TRUE without keyCertSign accepted as a signing CA. Intermediate CA certificates are required to have the keyCertSign key usage when a Key Usage extension is present, but chain-supplied temporary CAs WOLFSSLTEMPCA added while building a certificate path were previously exempt...

CVE-2026-6091
Partial-chain certificate verification may accept chains that terminate at a peer-supplied, untrusted intermediate certificate rather than a trusted anchor. An attacker could present a chain that ends at an intermediate they control and have it accepted as valid. This affects the OpenSSL...
node-forge: Forge (node-forge): Certificate validation bypass allows unauthorized certificate issuance
A flaw was found in Forge also known as node-forge, a JavaScript implementation of Transport Layer Security TLS. The pki.verifyCertificateChain function does not properly enforce certificate validation rules. This oversight allows an intermediate certificate that lacks specific security extension...
