Few moments back, we’ve been reported, the presence of a massive security hole in Facebook. The hole affects all users and threatens privacy. Within few clicks anyone can view your live chats, notifications, requests, etc. and this is extremely pathetic and embarrassing for people.

Facebook’s new preview feature to check out your profile virtualizing yourself to be anyone of your friend makes all their ‘stuff’ visible to yours and vice versa!

Here’s a video of the hole in action.

Update : Facebook has disabled chat to fix this hole.

For a limited period of time, a bug permitted some users’ chat messages and pending friend requests to be made visible to their friends by manipulating the “preview my profile” feature of Facebook privacy settings. When we received reports of the problem, our engineers promptly diagnosed it and temporarily disabled the chat function. We also pushed out a fix to take care of the visible friend requests which is now complete. Chat will be turned back on across the site shortly. We worked quickly to resolve this matter, ensuring that once the bug was reported to us, a solution was quickly found and implemented.

Update : Facebook chat is recovering!
