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.

CVE-2026-50632 is a high-severity vulnerability in Apache CXF related to improper input validation and deserialization of untrusted JMS configuration data. It stems from an incomplete fix of a previous issue (CVE-2026-44417) and allows untrusted users who can configure JMS to achieve arbitrary code execution, potentially leading to full system compromise. The vulnerability affects multiple Apache CXF versions prior to fixed releases 4.2.2, 4.1.7, and 3.6.12. Mitigation involves restricting JMS configuration access to trusted administrators only. Official patches are available in the specified fixed versions.

The fix for CVE-2025-48913: Apache CXF: Untrusted JMS configuration can lead to RCE was not complete, meaning that another path in the code might lead to code execution capabilities, if untrusted users are allowed to configure JMS for Apache CXF. Users are recommended to upgrade to versions 4.2.1, 4.1.6 or 3.6.11, which fix this issue.
