Description
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.

cxfapacheDetection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.cxf:cxf-rt-transports-jms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.apache.cxf:cxf-rt-transports-jms to 4.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-44417 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
This is an Important flaw in Apache CXF where an incomplete fix for a prior vulnerability allows remote code execution. Exploitation requires that untrusted users have permissions to configure Java Message Service (JMS) within the Apache CXF environment, which is not a default configuration in Red Hat products.…
To mitigate this issue, ensure that only trusted users have permissions to configure Java Message Service (JMS) for Apache CXF. Restrict access to configuration files and management interfaces that control JMS settings. If JMS functionality is not required, consider disabling it to remove the attack vector.Source: Red Hat security advisory for CVE-2026-44417 (CC BY 4.0)
