DescriptionNVD

A stored cross-site scripting (XSS) vulnerability exists in the web interface of Lyrion Music Server <= 9.0.3. An authenticated user with access to Settings Player can save arbitrary HTML/JavaScript in the Player name field. That value is stored by the server and later rendered without proper output encoding on the Information (Player Info) tab, causing the script to execute in the context of any user viewing that page.

RemediationAI

Encode all user-supplied output contextually (HTML, JS, URL). Implement Content Security Policy (CSP) headers. Use HTTPOnly and Secure cookie flags.
