AVideo YPTSocket Plugin Unauthenticated Cross-Site Scripting

Vulnerability Description
AVideo with YPTSocket plugin enabled contains a cross-site scripting vulnerability allowing unauthenticated attackers to execute arbitrary JavaScript in other users' browsers via the websocket callback mechanism.
