CVE-2021-32719

RabbitMQ is a multi-protocol messaging broker. In rabbitmq-server prior to
version 3.8.18, when a federation link was displayed in the RabbitMQ
management UI via the rabbitmq_federation_management plugin, its consumer
tag was rendered without proper <script> tag sanitization. This potentially
allows for JavaScript code execution in the context of the page. The user
must be signed in and have elevated permissions (manage federation
upstreams and policies) for this to occur. The vulnerability is patched in
RabbitMQ 3.8.18. As a workaround, disable the
rabbitmq_federation_management plugin and use CLI
tools instead.
