Facebook Privacy Bugs w/ New Design (techcrunch.com)

This bug has been around for at least 6 months, ever since just after the last major Facebook Profile redesign that moved profiles towards the 'Boxed' design.

For me, the bug lasted for at least an hour, or at least enough time for me to notice the bug, re-create a few friends lists, and browse a couple profiles. The next day when I logged on things were completely back to normal - AND my old friend lists had been restored.

One of the first things I noticed was that my friends lists had been deleted - and subsequently they no longer applied to photos privacy settings. Unfortunately I don't remember how or why I noticed this, maybe it was part of the exploratory feeling you get when something gets deactivated for a week and you want to make sure everything is OK.

The situatation also applied to my friends whose friends lists I was on. For example, if my friends didn't allow anyone to see tagged photos, I couldn't see their photos. But if my friend had just not allowed their 'Work friends' list to see their photos, and I was a Work friend, I could see their photos because my account no longer appeared under their friends lists entitled 'Work friends' - at least that's what I presume to have happened.

I do not recall if this affected the Networks as well. I don't recall if I was able to see normally private photos from strangers in other regional, high school or University networks. If it did, I probably would have a recollection of it because I did do some experimenting to see how far the bug extended.

Did I find any steamy secrets? Yes, in the form of insights into the nature of the human spirit and desire for privacy. And no, in regards to the underwhelming nature of photos. I should probably hang around in more exciting circles.


Actually I'm not sure this had anything to do with the new design. It may have been coincidence that the bug was found now (I'll try to find out).


This is just the tip of the iceberg. I've been picking at the new design for nearly a week and there is a host of security flaws and loopholes left there.

(up your privacy settings if you want to remain private!)


Why are they storing whose info I have access to see inside MY profile data and not within the profile data of the other user?


That's not necessarily what's happening. Another plausible explanation is that when you deactivate your account, you're removed from various lists in the profile data of all your friends. When you activate it again, you aren't put back on the list until a regularly scheduled task runs (or until data propogates through the servers?). So if one of the lists is "deny from seeing these photos", you get to see them until that happens.
