CVE-2026-50634
Last modified
CVE-2026-50634 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 0.28% chance of exploitation in the next 30 days.
