Subject: CVE-2025-31651: Apache Tomcat: Bypass of rules in Rewrite Valve

Severity: low

Affected versions:

- Apache Tomcat 11.0.0-M1 through 11.0.5
- Apache Tomcat 10.1.0-M1 through 10.1.39
- Apache Tomcat 9.0.0.M1 through 9.0.102

Description:

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.

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