Prior to 4.2.5, the RabbitMQ management UI renders the x-internal-purpose queue or exchange argument into an HTML title attribute without proper escaping on the Queues and Exchanges pages, allowing a user with permission to declare a queue or exchange to execute JavaScript in another user's browser. This issue is fixed in version 4.2.5."

Antes de la versión 4.2.5, la interfaz de usuario de gestión de RabbitMQ renderiza el argumento de cola o intercambio x-internal-purpose en un atributo HTML title sin el escape adecuado en las páginas de Colas e Intercambios, permitiendo a un usuario con permiso para declarar una cola o un intercambio ejecutar JavaScript en el navegador de otro usuario.
