CVE-2026-46605: Apache ActiveMQ improper authorization in destination removal

CVE-2026-46605 · Severity: medium · CVSS 4.3 · Published 2026-06-01

Apache ActiveMQ, a widely used open-source message broker for handling communication between different applications, contains a security flaw in how it verifies user permissions. An attacker who already has basic login credentials to the system can delete message destinations (queues or topics) that they should not have permission to modify. This could lead to service disruptions or data loss by removing the channels through which business applications communicate.

Technologies: Apache ActiveMQ, org.apache.activemq:apache-activemq (Maven). Vendors: Apache, Maven.

Technical details

An improper authorization vulnerability (CWE-285) exists in Apache ActiveMQ's destination removal workflow. The server fails to correctly validate permissions when an authenticated connection attempts to remove existing destinations (queues or topics). A remote attacker with low-privileged credentials can exploit this flaw to delete destinations, leading to a partial loss of availability. The issue is resolved in versions 5.19.7 and 6.2.6.
