Technical details
A stored cross-site scripting (XSS) vulnerability exists in Lyrion Music Server version 9.2.0 and earlier within the log viewer component. The application fails to properly sanitize input before it is rendered in the web-based log interface, specifically targeting unescaped template variables. Attackers can trigger the vulnerability by providing malicious payloads through URL query parameters (search, lines, path) or by forcing the server to log crafted strings such as malicious User-Agent headers, stream titles, or player names. Because the logging of these values can often be triggered without authentication, a remote attacker can store a script that executes in the context of any user (typically an administrator) who later views the server logs.
