Versions Affected: Apache Tomcat 11.0.0-M1 to 11.0.21 Apache Tomcat 10.1.0-M1 to 10.1.54 Apache Tomcat 9.0.0.M1 to 9.0.117 Older, unsupported versions may also be affected
Description: When multiple security constraints defined an HTTP method constraint for the same extension pattern, only the first method constraint was applied.
Mitigation: Users of the affected versions should apply one of the following mitigations:

- Upgrade to Apache Tomcat 10.1.55 or later
- Upgrade to Apache Tomcat 9.0.118 or later
