A flaw was found in RabbitMQ, a messaging and streaming broker. Unsanitized virtual host names allow for XSS in the the management UI pages that list virtual hosts if the attacker manages to find a way to force a virtual host to restart. This vulnerability requires high privileges and user interaction, potentially leading to a low impact on confidentiality and integrity.
