CVE-2026-67233 · Severity: info · Published 2026-09-24

RabbitMQ is a message broker used to route data between applications. The shovel plugin enables replicating messages across brokers. A user with read-only monitoring credentials can delete or restart shovels, a state-changing operation that should be restricted to administrators, bypassing role-based access controls.

## Technical details

The shovel management resource's is_authorized/2 function delegates authorization to rabbit_mgmt_util:is_authorized_monitor/2, which accepts the monitoring tag. However, allowed_methods includes DELETE, and delete_resource/2 removes shovel parameters without additional role verification. An attacker with monitoring credentials and access to affected vhosts can invoke state-changing operations that the /api/parameters endpoint correctly restricts to policymaker role. The vulnerability requires rabbitmq_shovel and rabbitmq_shovel_management plugins to be enabled.
