  - In rabbitmq-server prior to version 3.8.17, a new user being added via management UI could lead to the user's bane
    being rendered in a confirmation message without proper `<script>` tag sanitization, potentially allowing for
    JavaScript code execution in the context of the page. (CVE-2021-32718)

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