A vulnerability in Apache CXF's JwsJsonContainerRequestFilter allows processing of metadata that was not authenticated by the accepted signature. This bypasses the application's assumption that certain HTTP header metadata is verified, potentially affecting downstream entity parsing or signed-header checks. The issue is fixed in Apache CXF versions 4.2.2 and 4.1.7.
AI Analysis
Technical Summary
CVE-2026-50634 is a vulnerability in Apache CXF's JwsJsonContainerRequestFilter component. It allows an attacker to cause CXF to process metadata that was not authenticated by the accepted signature, bypassing the application's trust in the authenticity of Content-Type or protected HTTP-header metadata. This can affect downstream JAX-RS entity parsing or signed-header consistency checks, potentially leading to integrity issues. The vulnerability is addressed by upgrading to Apache CXF versions 4.2.2 or 4.1.7.
Potential Impact
The vulnerability can lead to CXF processing unauthenticated metadata, which may cause the application to trust manipulated HTTP headers or content types. This undermines the integrity assumptions of the application and could lead to incorrect processing of requests. The CVSS score of 6.5 (medium severity) reflects a network attack vector with low complexity and no privileges required, impacting confidentiality and integrity but not availability.
Mitigation Recommendations
Users should upgrade Apache CXF to versions 4.2.2 or 4.1.7, where this vulnerability is fixed. No other mitigation is indicated. Patch status is confirmed by the vendor advisory recommending these versions.
