CVE-2026-46605

A flaw was found in Apache ActiveMQ server. An authenticated attacker with proper permissions could exploit an incomplete authorization vulnerability to remove existing destinations. This could lead to a Denial of Service (DoS) by disrupting message delivery and processing.

Red Hat products ship Apache ActiveMQ Classic components as transitive dependencies. The vulnerability requires running a Classic ActiveMQ broker with multi-user authentication — an authenticated user can remove destinations without proper authorization. Red Hat AMQ Broker is based on Apache ActiveMQ Artemis, a separate codebase. The Classic broker is not deployed as a standalone service in Red Hat products, and the vulnerable authorization code path is not exercised at runtime.
