ARTEMIS-5996: CVE-2026-40914: Apache Artemis, Apache ActiveMQ Artemis: Address routing-type can be updated by STOMP protocol user without the createAddress permission

[Justin Bertram <jbertram () apache org>]

Severity: low 

Affected versions:

- Apache Artemis (org.apache.artemis:artemis-stomp-protocol) 2.50.0 through 2.53.0
- Apache ActiveMQ Artemis (org.apache.artemis:artemis-stomp-protocol) 2.0.0 through 2.44.0

Description:

A vulnerability exists in Apache Artemis whereby an application using the STOMP protocol with security credentials that 
grant either the consume or send permission on an address can augment the routing-type supported by that address even 
if said user doesn't have the createAddress permission for that particular address. A user could successfully send a 
message to an address or consume a message from a queue with a routing-type not supported by the corresponding address 
when that operation should actually be rejected on the basis that the user doesn't have permission to change the 
routing-type of the address. Even though the user was already granted permission to send and/or consume messages, they 
should not be able to augment the routing-type of the address without the createAddress permission.



This issue affects Apache Artemis: from 2.50.0 through 2.53.0; Apache ActiveMQ Artemis: from 2.0.0 through 2.44.0.

Users are recommended to upgrade to version 2.54.0, which fixes the issue.

This issue is being tracked as ARTEMIS-5996
