CVE-2026-24734 is an improper certificate-validation vulnerability in Apache Tomcat Native and Apache Tomcat's Foreign Function and Memory port of Tomcat Native code. When configured to use an OCSP responder, affected versions do not complete verification or freshness checks for OCSP responses. This can permit certificate revocation checks to be bypassed, undermining TLS certificate trust decisions.
