CVE-2026-40914: CWE-863 Incorrect Authorization in Apache Software Foundation Apache Artemis Stomp Protocol
CVE-2026-40914 is a medium severity vulnerability in Apache Artemis affecting versions 2.50.0 through 2.53.0 and Apache ActiveMQ Artemis 2.0.0 through 2.44.0. It involves incorrect authorization in the STOMP protocol where users with send or consume permissions can modify the routing-type of an address without having the createAddress permission. This could lead to unauthorized changes in message routing behavior. No official patch or remediation guidance is currently available.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-40914) in Apache Artemis and Apache ActiveMQ Artemis arises from improper authorization checks in the STOMP protocol implementation. Specifically, users who have send or consume permissions can augment the routing-type of an address without requiring the createAddress permission, violating intended access controls. The affected versions include Apache Artemis 2.50.0 through 2.53.0 and Apache ActiveMQ Artemis 2.0.0 through 2.44.0. The CVSS v3.1 base score is 4.3 (medium severity), reflecting limited impact on confidentiality and availability but some impact on integrity. No vendor advisory or patch information is currently provided.
Potential Impact
The vulnerability allows users with send or consume permissions to alter the routing-type of an address without proper authorization. This could lead to unauthorized modification of message routing behavior within the messaging system, potentially impacting message integrity. There is no indication of impact on confidentiality or availability. No known exploits in the wild have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, review and restrict permissions for users with send or consume rights to minimize risk. Monitor vendor channels for updates and apply patches promptly once available.
