BuddyPress Instant Chat <= 1.6 - Unauthenticated Stored XSS via Chat Message
The BuddyPress Instant Chat WordPress plugin through 1.6 does not check that the sender of a chat message belongs to the conversation it is being added to, nor does it escape message content before outputting it back, allowing unauthenticated users to store arbitrary web scripts that will execute in the session of any member who later views that conversation.
