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.
