CVE-2026-32642: Apache Artemis: Unauthorized Temporary Address Creation via OpenWire Protocol

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.
