"The version of RabbitMQ installed on the remote host is 4.2.x prior to 4.2.5. It is, therefore, affected by a
cross-site scripting vulnerability:

  - 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. (CVE-2026-57214)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
