this vulnerability and Patrik Ragnarsson from CloudAMQP for contributing a fix.

Impact

When a federation link was displayed in the RabbitMQ management UI via the rabbitmq_federation_management plugin,
its consumer tag was rendered without proper <script> tag sanitization, potentially allowing for JavaScript code
execution in the context of the page.

The user must be signed in and have elevated permissions (manage federation upstreams and policies).

  • #3122

Workarounds
