Workaround: No mitigation is currently available that meets Red Hat Product Security’s standards for usability, deployment, applicability, or stability.

To reduced the risk, by disabling or strictly limiting the use of HTTP PUT requests to trusted, authenticated users only. Additionally, administrators should review and adjust URL rewrite rules to ensure they do not manipulate request paths in ways that could expose protected directories such as /WEB-INF/ or /META-INF/. Implementing strict access controls and monitoring for unexpected rewrite or upload behavior can further minimize potential exploitation.
