Description

1) Improper authorization (CVE-ID: CVE-2026-24734)
CWE-ID: CWE-285 - Improper Authorization
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to bypass authorization checks.
The vulnerability exists due to incomplete OCSP verification checks. When using an OCSP responder, Tomcat's FFM integration with OpenSSL does not complete verification or freshness checks on the OCSP response. A remote attacker can bypass certificate revocation and gain unauthorized access to the application.
