Facebook exploit reveals live chat contents [Video]

Facebook's security settings have again come under the microscope, as an exploit that can expose not only pending friend requests but contents of live chat conversations.  TechCrunch aren't revealing the exact mechanism by which the exploit works, but it seems that the system Facebook have for previewing your own profile's appearance to others can also be used to see the details of other users.

Facebook are yet to comment on the situation, but there are reports that some users have already found live chat to be disabled on their accounts.  The assumption is that there is some speedy background tinkering going on to try to curtail the hole.
