Apache CXF: WS JSON request filter trusts metadata from an unvalidated first signature entry
CVE-2026-50634 · GHSA-33j8-j763-4fv5
- Affected
- Maven org.apache.cxf:cxf-rt-rs-security-jose-jaxrs >= 4.2.0, < 4.2.2; < 4.1.7
- Fixed in
- 4.2.24.1.7· Vendor fix available
- Issue
- 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.
Recommended action: Upgrade to 4.2.2 or 4.1.7 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
