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

CVE ID :CVE-2026-50634

Published : June 12, 2026, 10:16 a.m. | 1 hour, 6 minutes ago

Description :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, which fix this issue.

Severity: 0.0 | NA
