CVE-2026-57221

RabbitMQ is a messaging and streaming broker. Prior to 3.13.15, 4.0.20, 4.1.11, and 4.2.6, RabbitMQ does not perform authorization checks on passive queue.declare and exchange.declare AMQP 0-9-1 operations, allowing any authenticated user who can connect to a virtual host to enumerate queue and exchange names and read queue message and consumer counts. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6.
