Description

Our team would like to thank Christian Rellmann from usd AG for responsibly disclosing
the vulnerability and helping us verify a fix.

Impact

When a new user was added via management UI, its name was rendered in a confirmation
message without proper <script> tag sanitization, potentially allowing for JavaScript code
execution in the context of the page.

The user must be signed in and have elevated permissions (other user management).

Patches

Workarounds

Disable rabbitmq_management plugin and use CLI tools for management operations
and Prometheus and Grafana for metrics and monitoring.
