NVD Description

Note: Versions mentioned in the description apply only to the upstream tomcat-jsvc package and not the tomcat-jsvc package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

CLIENT_CERT authentication does not fail as expected for some scenarios when soft fail is disabled and FFM is used in Apache Tomcat.

This issue affects Apache Tomcat: from 11.0.0-M14 through 11.0.20, from 10.1.22 through 10.1.53, from 9.0.92 through 9.0.116.

Users are recommended to upgrade to version 11.0.21, 10.1.54 or 9.0.117, which fixes the issue.
