It's not a bug (well, not in the classic sense), and it's not new
behaviour.

su complains "su: must be run from a terminal", and this helps point
towards the underlying issue. When you run ssh with a command argument,
it does not (by default) create a terminal. This means there's no way
to disable echo, so sudo ends up prompting with a visible password.
The solution is to force ssh to allocate a pseudo-tty, with the -t flag:
ssh -t [EMAIL PROTECTED] sudo ls
