{"id":"CVE-2026-89135","summary":"Failed X509_verify_cert leaves unverified CA in shared CertManager","details":"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.","modified":"2026-10-01T03:30:20.713672680Z","published":"2026-09-27T09:14:44.599Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89135.json","cna_assigner":"wolfSSL","cwe_ids":["CWE-295"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89135.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89135"},{"type":"FIX","url":"https://github.com/wolfSSL/wolfssl/pull/11009"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wolfssl/wolfssl","events":[{"introduced":"59f4fa568615396fbf381b073b220d1e8d61e4c2"},{"fixed":"ac01707f552c611fbd135cc723b2682b3e7f80f2"}],"database_specific":{"extracted_events":[{"introduced":"5.8.4"},{"last_affected":"5.9.2"},{"fixed":"5.9.2"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v5.9.1-stable","v5.9.0-stable","v5.8.4-stable","wolfEntropy2d"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89135.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
