Missing Authentication — Artemis CORE CREATE_QUEUE(34) on ch1 creates durable queue pre-auth (JBoss EAP)

Missing authentication on the Artemis CORE protocol channel: an unauthenticated attacker can send CREATE_QUEUE packets on channel 1 via the :8080 HTTP-upgrade path to create arbitrary durable JMS queues on the embedded broker, enabling resource exhaustion and persistent broker-state manipulation without any credentials.
