CVE-2026-50634

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.

Summary		(es) Una vulnerabilidad en el JwsJsonContainerRequestFilter de Apache CXF puede ser explotada para hacer que CXF procese metadatos que no fueron autenticados por la firma aceptada. Esto puede eludir la suposición de la aplicación de que los metadatos de ’Content-Type’ aceptados o de encabezado HTTP protegido provenían de una entrada de firma verificada, y puede dirigir el análisis de entidades JAX-RS posterior o las comprobaciones de coherencia de encabezados firmados. Se recomienda a los usuarios actualizar a las versiones 4.2.2 o 4.1.7, que solucionan este problema.
