Description
ejabberd team reports: Fixed issue with handling of user provided occupant-id in messages and presences sent to muc room. Server was replacing just first instance of occupant-id with its own version, leaving other ones untouched. That would mean that depending on order in which clients send occupant-id, they could see value provided by sender, and that could be used to spoof as different sender.
