CVE-2026-66076

RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0, isauthorized/2 calls rabbitmgmtutil:isauthorized/2, which checks only the management tag, instead of isauthorizedvhost/2. The /api/queues/quorum/:vhost/:queue/status handler reads the vhost...
