For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: To mitigate this issue, review Apache Tomcat's rewrite valve configurations. If the rewrite valve is not essential for your application, consider disabling it. If it is required, ensure its configuration does not permit improper URL encoding that could lead to security constraint bypasses. A service restart may be required for changes to take effect. Workaround: To mitigate this issue, ensure that the EncryptInterceptor in Apache Tomcat is configured according to secure best practices.
