Affected packages

• Maven org.apache.cxf:cxf-rt-rs-security-jose-jaxrs: >= 4.2.0, < 4.2.2 → fixed in 4.2.2 • Maven org.apache.cxf:cxf-rt-rs-security-jose-jaxrs: < 4.1.7 → fixed in 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.
