Answer in brief
CVE-2026-50634 records a Unknown severity vulnerability in Apache CXF: WS JSON request filter trusts metadata from an unvalidated first signature entry. The current sources do not mark it as known exploited. The current feed maps Apache Software Foundation/Apache CXF (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
