Apache Tomcat: Bypass of rules in Rewrite Valve

Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache Tomcat. For a subset of unlikely rewrite rule configurations, it was possible 
for a specially crafted request to bypass some rewrite rules. If those 
rewrite rules effectively enforced security constraints, those 
constraints could be bypassed.

This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.5, from 10.1.0-M1 through 10.1.39, from 9.0.0.M1 through 9.0.102.
The following versions were EOL at the time the CVE was created but are 
known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions 
may also be affected.


Users are recommended to upgrade to version [FIXED_VERSION], which fixes the issue.
