Summary
AVideo YPTSocket Plugin Unauthenticated Cross-Site Scripting
Details

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. Attackers can send crafted socket messages with callback names resolving to global functions like avideoConfirmHTML that accept untrusted data and assign it to innerHTML, achieving script execution in the victim's origin without authentication or user interaction.
