Apache CXF: WS JSON request filter trusts metadata from an unvalidated first signature entry_CVE-2026-50634

{
    "lastseen": "",
    "description": "A vulnerability in Apache CXF's\u00a0JwsJsonContainerRequestFilter can be exploited to cause\u00a0CXF to process metadata that was not authenticated by the accepted signature.\u00a0This can bypass the application's assumption\n\nthat 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, which fix this issue.",
