Forum [URGENT] Serious problem with my Forum
 

Hi there I have just been contacted by a member on my forum, they have just logged into there own account using there own details, but once they have actually logged in they are logged in as one of our Admins.

I have had to close the forum as this poses a serious security risk for the site.

This has only happened to this member today no plugins have been added recently, so is this a bug with VB4 or something else?

I could disable all plugins in the config, but am weary of reopening the forum incase an unsavory member decides to try and access the CP and or the private staff rooms.
