Doc Text:	A flaw was found in Apache Artemis and Apache ActiveMQ Artemis. An authenticated user can exploit this incorrect authorization vulnerability by attempting to create a non-durable Java Message Service (JMS) topic subscription on an address that does not exist. If the user has "createDurableQueue" permission but lacks "createAddress" permission, and address auto-creation is disabled, a temporary address will be unexpectedly created. This bypasses intended authorization, allowing for unauthorized resource creation.	Story Points:	---

Description OSIDB Bzimport 2026-03-24 09:01:49 UTC

Incorrect Authorization (CWE-863) vulnerability in Apache Artemis, Apache ActiveMQ Artemis exists when an application using the OpenWire protocol attempts to create a non-durable JMS topic subscription on an address that doesn't exist with an authenticated user which has the "createDurableQueue" permission but does not have the "createAddress" permission and address auto-creation is disabled. In this circumstance, a temporary address will be created whereas the attempt to create the non-durable subscription should instead fail since the user is not authorized to create the corresponding address. When the OpenWire connection is closed the address is removed.

This issue affects Apache Artemis: from 2.50.0 through 2.52.0; Apache ActiveMQ Artemis: from 2.0.0 through 2.44.0.

Users are recommended to upgrade to version 2.53.0, which fixes the issue.
