Details

Always-Incorrect Control Flow Implementation vulnerability in Apache Tomcat's rewrite valve meant that if the first condition in an OR chain matched, subsequent non-OR conditions were skipped.

This issue affects Apache Tomcat: from 11.0.0 through 11.0.22, from 10.1.0 through 10.1.55, from 9.0.0 through 9.0.118, from 8.5.0 through 8.5.100. Other versions that have reached end of support may also be affected.
