CVE-2025-65229

6th percentile - higher than 6% of all known CVEs

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.

An attacker can inject a malicious script that executes in other users' browsers, potentially leading to session hijacking, credential theft, or other sensitive information disclosure. It may also enable further attacks within the victim's browser context.

Update Lyrion Music Server to a version later than 9.0.3 if available. If not, restrict access to player settings to trusted users only and consider disabling the player name editing feature.
