Description

RabbitMQ is a messaging and streaming broker. 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.
