Summary

Apache ActiveMQ and its Runtime Config plugin are affected: after a principal's write permission on a destination is removed at runtime, an already-authenticated connection opened before the change can keep sending to that destination, including through a new anonymous producer. Fresh connections and new explicit producers are correctly denied, and the advisory notes that the setup involves the runtime configuration plugin.
