Description OSIDB Bzimport 2026-09-23 11:33:26 UTC 
Improper Check for Certificate Revocation vulnerability in Apache Tomcat. Both the OpenSSL and OpenSSL-FFM TLS implementations ignore CRLs when certificate uses a keystore.



This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.25, from 10.1.0-M1 through 10.1.58, from 9.0.0-M1 through 9.0.121.



The following versions were EOL at the time the CVE was created but are 
known to be affected: from 8.5.0 through 8.5.100. Other unsupported versions may also be affected.



Users are recommended to upgrade to version 11.0.26, 10.1.59, 9.0.122, which fixes the issue.
