Description

Lyrion Music Server 9.2.0 contains an unauthenticated stored cross-site scripting vulnerability in the log viewer that allows attackers to inject malicious scripts by exploiting unescaped template variables. Attackers can inject XSS payloads through search, lines, and path query parameters or by crafting values that get logged such as URLs, User-Agent headers, stream titles, or player names to execute arbitrary scripts in users' browsers.
