I don't know if you read it, but I sent you an email about this same bug (when I originally found it in Drupal) in 2012. Didn't know FB was vulnerable back then. By the way, I learned a lot from you here on HN. So let me take this opportunity and say thank you very much.

I did! I responded to your first mail, too! :)

When I saw your name, it looked familiar, and I went and looked up your old mail. Great work! Congrats on an awesome finding.
