Summary
An unauthenticated network attacker can delete arbitrary durable queues on any Apache Artemis broker with OpenWire protocol enabled (default). The processRemoveSubscription() method executes pre-authentication with no authorization check, and uses the internal destroyQueue(SimpleString) overload that skips security entirely.
Default queues DLQ and ExpiryQueue are trivially targetable. This is unfixed in all Artemis versions through 2.55.0.
Red Hat severity: Important — CVSS 8.2 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H). Weakness: CWE-306.
Affected Red Hat products: Red Hat AMQ Broker 7; Red Hat JBoss Enterprise Application Platform Expansion Pack. Red Hat lists Red Hat build of Apache Camel for Spring Boot 4; Red Hat JBoss Enterprise Application Platform 7; Red Hat JBoss Enterprise Application Platform 8 as not affected.
Red Hat does not currently list a fixing RHSA for this CVE.

Mitigation checklist
- 1. Remove OpenWire from acceptors — edit broker.xml, remove OPENWIRE from protocols parameter 2. Firewall — restrict port 61616 to trusted clients if OpenWire cannot be disabled 3. Monitor — watch for "AMQ601069: destroyed queue: <name>" in broker logs
