Description
Libredesk is a self-hosted customer support desk. Prior to version 0.8.6-beta, LibreDesk is vulnerable to stored HTML injection in the contact notes feature. When adding notes via POST /api/v1/contacts/{id}/notes, the backend automatically wraps user input in tags. However, by intercepting the request and removing the tag, an attacker can inject arbitrary HTML elements such as forms and images, which are then stored and rendered without proper sanitization. This can lead to phishing, CSRF-style forced actions, and UI redress attacks. This issue has been patched in version 0.8.6-beta.
