CVE-2026-61837: RabbitMQ AMQP 1.0 management binding enumeration

CVE-2026-61837 · Severity: info · Published 2026-09-25

RabbitMQ is a message broker that routes messages between applications. The AMQP 1.0 management interface allows any authenticated user to enumerate the complete routing topology (exchanges, queues, and routing rules) of their virtual host, even if they lack management permissions. This exposes sensitive infrastructure details that should be restricted to administrators.

Technical details

The GET /bindings endpoint in the AMQP 1.0 management module (rabbitamqpmanagement handler) fails to perform resource-level permission checks, unlike sibling operations. Authenticated AMQP 1.0 clients without management tags can invoke this endpoint to retrieve full binding topology including source exchanges, destination queues, routing keys, and binding arguments. The fix adds resource access validation aligned with other binding handlers.
