A fix is available — apply it.

A vulnerability in Apache CXF's JwsJsonContainerRequestFilter can be exploited to cause CXF to process metadata that was not authenticated by the accepted signature. This can bypass the application's assumption

that accepted Content-Type or protected HTTP-header metadata came from a verified signature entry, and may steer downstream JAX-RS entity parsing or signed-header consistency checks. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fix this issue.
