CVE-2026-57213 PUBLISHED

RabbitMQ: Stored XSS federation management plugin via unsanitized consumer_tag rendering

Assigner: GitHub_M
Reserved: 24.06.2026 Published: 10.07.2026 Updated: 10.07.2026

RabbitMQ is a messaging and streaming broker. Prior to 3.13.14, 4.0.19, 4.1.10, and 4.2.5, the rabbitmq_federation_management plugin renders the consumer_tag field on the Federation Status page without HTML escaping, allowing a user who can configure a federation upstream or policy to execute JavaScript in the browser of a user viewing that page. This issue is fixed in versions 3.13.14, 4.0.19, 4.1.10, and 4.2.5.
