CVE-2026-89135

Failed X509_verify_cert leaves unverified CA in shared CertManager PUBLISHED

Description (CNA)

A failed X509_verify_cert call permanently plants an unverified attacker CA in the shared CertManager, bypassing certificate validation in every type-blind sibling consumer (native TLS, OCSP, CRL, direct CM verify). This affects version 5.8.4 through 5.9.2 of wolfSSL with the macros (OPENSSL_EXTRA && !NO_CERTS && !WOLFCRYPT_ONLY) defined or built with --enable-opensslextra and the application is specifically making calls to the X509_verify_cert function.
