"The version of rabbitmq-server installed on the remote Azure Linux 3.0 host is prior to tested version. It is,
therefore, affected by a vulnerability as referenced in the CVE-2025-30219 advisory.

  - RabbitMQ is a messaging and streaming broker. Versions prior to 4.0.3 are vulnerable to a sophisticated
    attack that could modify virtual host name on disk and then make it unrecoverable (with other on disk file
    modifications) can lead to arbitrary JavaScript code execution in the browsers of management UI users.
    When a virtual host on a RabbitMQ node fails to start, recent versions will display an error message (a
    notification) in the management UI. The error message includes virtual host name, which was not escaped
    prior to open source RabbitMQ 4.0.3 and Tanzu RabbitMQ 4.0.3, 3.13.8. An attack that both makes a virtual
    host fail to start and creates a new virtual host name with an XSS code snippet or changes the name of an
    existing virtual host on disk could trigger arbitrary JavaScript code execution in the management UI (the
    user's browser). Open source RabbitMQ `4.0.3` and Tanzu RabbitMQ `4.0.3` and `3.13.8` patch the issue.
