CVE-2021-32719

RabbitMQ is a multi-protocol messaging broker. In rabbitmq-server prior to version 3.8.18, 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. This potentially allows 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) for this to occur. The vulnerability is patched in RabbitMQ 3.8.18. As a workaround, disable the `rabbitmq_federation_management` plugin and use [CLI tools](https://www.rabbitmq.com/cli.html) instead.

RabbitMQ es un broker de mensajería multiprotocolo. En rabbitmq-server versiones anteriores a 3.8.18, cuando un enlace de federación es mostrado en la Interfaz de Usuario de administración de RabbitMQ por medio del plugin "rabbitmq_federation_management", su etiqueta consumer se mostraba sin el saneamiento apropiado de la etiqueta (script). Esto permite potencialmente una ejecución de código JavaScript en el contexto de la página. El usuario debe haber iniciado sesión y tener permisos elevados (gestionar flujos ascendentes y políticas de federación) para que esto ocurra. La vulnerabilidad está parcheada en RabbitMQ versión 3.8.18. Como solución alternativa, desactivar el plugin "rabbitmq_federation_management" y usar [CLI tools](https://www.rabbitmq.com/cli.html) en su lugar
