Severity: important Affected versions:
- Apache CXF (org.apache.cxf:cxf-rt-rs-security-jose-jaxrs) 4.2.0 before 4.2.2 - Apache CXF (org.apache.cxf:cxf-rt-rs-security-jose-jaxrs) before 4.1.7 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. Credit: Mitchell Benjamin / Revamp Studio.
