Moderate: OCSP checks sometimes soft-fail with FFM even when soft-fail is disabled CVE-2026-34500 CLIENTCERT authentication did not fail as expected for some scenarios when soft fail was disabled and FFM was used. This was fixed with commit c13e60e7. This issue was reported to the Tomcat security...
Improper Verification of Cryptographic Signature
Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature in the OCSP response validation process. An attacker can bypass certificate revocation checks by providing a forged OCSP response, potentially enabling man-in-the-middle attacks...
CVE-2026-32883
Botan is a C++ cryptography library. From version 3.0.0 to before version 3.11.0, during X509 path validation, OCSP responses were checked for an appropriate status code, but critically omitted verifying the signature of the OCSP response itself. This issue has been patched in version 3.11.0...
CVE-2026-32883
CVE-2026-32883 affects the Botan C++ cryptography library. From version 3.0.0 through before 3.11.0, during X509 path validation, OCSP responses were checked for a valid status but the OCSP response signature itself was not verified, enabling a potential Man‑in‑the‑Middle in certificate revocatio...
BIT-NGINX-2026-28755 NGINX ngx_stream_ssl_module vulnerability
NGINX Plus and NGINX Open Source have a vulnerability in the ngxstreamsslmodule module due to the improper handling of revoked certificates when configured with the sslverifyclient on and sslocsp on directives, allowing the TLS handshake to succeed even after an OCSP check identifies the...
tomcat: Apache Tomcat: Certificate revocation bypass due to improper OCSP response validation
A flaw was found in Apache Tomcat. When an Online Certificate Status Protocol OCSP responder is used, the Tomcat Native component, and Tomcat's FFM port of the Tomcat Native code, does not properly verify or check the freshness of the OCSP response. This improper input validation vulnerability...
