CVE-2026-44417: Apache CXF: Incomplete fix for CVE-2025-48913 (Untrusted JMS configuration can lead to RCE)

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.

Security readout for executives and security teams

Plain-English summary

Apache CXF, a common Java framework for building web services, has a flaw where an attacker who can influence how JMS messaging is configured could run code on the server. This is an incomplete fix for an earlier issue (CVE-2025-48913), meaning a different code path can still be abused. Apache has released patched versions.

Executive priority

Prioritize patching within the standard high-severity SLA. Impact is significant where CXF-based services accept externally influenced JMS configuration, but attack complexity is high and no active exploitation is reported, so this is important remediation rather than an emergency.

Technical view

Untrusted JMS configuration in Apache CXF's cxf-rt-transports-jms transport can lead to remote code execution. The earlier remediation for CVE-2025-48913 did not cover all code paths, leaving a residual RCE vector when attackers control JMS configuration inputs. Affected releases include Apache CXF 4.2.0, 4.1.x prior to 4.1.6, and 3.6.x prior to 3.6.11. CVSS 3.1 is 7.5 (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). CWE-15 and CWE-20 apply.

Likely exposure

Organizations running Java services built on Apache CXF that expose JMS transport configuration to user-supplied or externally influenced inputs. Red Hat products embedding CXF (per RHSA-2026:37390) and downstream integrations that permit dynamic JMS endpoint or destination configuration are the most likely exposure surface.

Exploitation context

No public exploit or active exploitation is cited in the source bundle, and the CVE is not listed in CISA KEV. The CVSS vector indicates high attack complexity and requires low privileges, so exploitation depends on an attacker being able to supply or influence JMS configuration values processed by CXF.

Researcher notes

This is a follow-up to CVE-2025-48913 where the original patch missed an alternate code path leading to RCE via untrusted JMS configuration. CWE-15 (external control of system or configuration setting) and CWE-20 (improper input validation) frame the root cause. Validate whether hardening applied for the prior CVE still applies, and confirm no custom JMS ConnectionFactory or destination lookup logic reintroduces the sink after upgrade.

Mitigation direction

  • Upgrade Apache CXF to 4.2.1, 4.1.6, or 3.6.11 per the Apache advisory.
  • Apply Red Hat RHSA-2026:37390 updates on affected Red Hat product deployments.
  • Restrict who can supply or modify JMS transport configuration to trusted administrators only.
  • Review applications for endpoints that accept JMS configuration from untrusted callers and gate them behind authorization.
  • Consult vendor guidance for any embedded CXF distributions not yet patched.

Validation and detection

  • Inventory Java services and dependencies for org.apache.cxf:cxf-rt-transports-jms and confirm version.
  • Compare deployed CXF versions against fixed releases 4.2.1, 4.1.6, and 3.6.11.
  • Check Red Hat product errata (RHSA-2026:37390) status for applicable Red Hat installations.
  • Audit application code and configuration pipelines for user-controllable JMS parameters.
  • Monitor vendor advisories and Red Hat Bugzilla RHBZ#2480729 for updates on completeness of the fix.
