Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache CXF (org.apache.cxf:cxf-rt-transports-http and org.apache.cxf:apache-cxf) versions 3.2.0 before 3.2.5 and before 3.1.16 do not properly report TLS hostname verification failures when the com.sun.net.ssl implementation is enabled through the java.protocol.handler.pkgs system property. An attacker in a man-in-the-middle position can then intercept connections from a CXF client without the error being raised. Upgrade to version 3.2.5 or 3.1.16.
