CVE-2026-57221 Details
Description
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.
An authorization bypass vulnerability has been identified in RabbitMQ versions prior to 3.13.15, 4.0.20, 4.1.11, and 4.2.6. The issue arises because RabbitMQ does not enforce authorization checks on passive 'queue.declare' and 'exchange.declare' operations in AMQP 0-9-1. This oversight allows any authenticated user with a connection to a virtual host to enumerate queue and exchange names, as well as access queue message and consumer counts. The vulnerability exploits the absence of 'configure' permission checks, enabling users with minimal permissions to gain insights into the messaging system's structure and activity.
Users can upgrade to RabbitMQ versions 3.13.15, 4.0.20, 4.1.11, or 4.2.6, where this vulnerability has been patched.
