CVE-2026-50634
mediumpriority · track · 0EPSS 0.003 · 20 %ileDEEUFRUSEPSS · scored 2026-10-27
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.
