CVE-2026-61837Public exploitNetwork attack vectorHinoki check available

Authenticated topology disclosure via missing binding authorization

Published Sep 25, 2026 · Updated Sep 25, 2026

Missing authorization in RabbitMQ Server allows remote authenticated users to read complete virtual-host binding topology through AMQP 1.0. The rabbit_amqp_management GET /bindings handler ignores the authenticated User and returns unfiltered binding records without calling resource-access checks. Any AMQP 1.0 account with virtual-host access and a paired management link can obtain exchange, queue, routing-key, and binding-argument details; integrity and availability are unaffected.
