Search: CVE-2026-66909

Apache CXF's JMS transport component is vulnerable to deserialization of untrusted data via JMS ObjectMessage bodies. This vulnerability allows an attacker who can send messages to the JMS destination to submit malicious serialized objects, potentially causing denial of service or remote code execution if a suitable gadget class is present. The issue is fixed by disabling ObjectMessage deserialization by default and providing a configuration option to re-enable it if necessary. Users should upgrade to Apache CXF versions 4.2.3, 4.1.8, or 3.6.12 to address this vulnerability.
