MyBB Community Forums

So I installed MyBB on my forum, and when I logged into the Admin account, it said my password was compromised.
This was a fresh install.. 

This also happens with EVERY fresh MyBB forum install. 
Is there a known exploit in MyBB? Or is Chrome just broken?

(This also happens if I register on forums with no SSL.)
