CVE-2026-67412: RabbitMQ Federation upstream authorization bypass

CVE-2026-67412 · Severity: info · Published 2026-09-25

RabbitMQ is a messaging broker that organizations use to route and queue messages. Federation allows multiple RabbitMQ instances to share messages across organizational boundaries. A policy administrator configured on one isolated virtual host can bypass permission checks and read or drain messages from other virtual hosts they should not have access to, potentially exposing sensitive messages or causing message loss.

Technical details

The Federation upstream feature in RabbitMQ fails to validate virtual host authorization when processing upstream URIs, allowing a principal with policy configuration rights on one vhost to access and drain messages from other vhosts. An attacker with vhost-level policy permissions can invoke federation without proper access control, reading or consuming messages across vhost boundaries. The vulnerability is fixed in patched versions.
