Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

wwbn/avideo versions up to and including 29.0 are affected. An unauthenticated attacker can connect to the YPTSocket WebSocket server and send a crafted message that is relayed to a chosen logged-in user, whose browser evaluates it as JavaScript. The earlier fix is incomplete, and no fixed version is listed.
