CVE-2026-34500

A flaw was found in Apache Tomcat where OCSP-based certificate validation may incorrectly soft-fail during CLIENTCERT authentication, even when soft-fail is disabled, under certain FFM-related execution paths. This can result in client certificates being accepted despite failed or unverifiable...

CVE-2026-5194

A flaw was found in wolfSSL. Missing hash/digest size and Object Identifier OID checks allow the acceptance of smaller, less secure digests during the verification of Elliptic Curve Digital Signature Algorithm ECDSA certificates. This could enable a remote attacker, with knowledge of the public...

CVE-2026-5194

Missing hash/digest size and OID checks allow digests smaller than allowed when verifying ECDSA certificates, or smaller than is appropriate for the relevant key type, to be accepted by signature verification functions. This could lead to reduced security of ECDSA certificate-based authentication...

CVE-2026-34500

CVE-2026-34580 Botan has a certificate authentication bypass due to trust anchor confusion

Botan is a C++ cryptography library. In 3.11.0, the function CertificateStore::certificateknown had a misleading name; it would return true if any certificate in the store had a DN and subject key identifier, if set matching that of the argument. It did not check that the cert it found and the ce...
