The vulnerability was discovered by security researcher Dan Melamed in June 2016. It allows a bad actor the ability to delete videos on Facebook without permission or authentication. Facebook, patched the vulnerability a short time after Melamed reported the flaw to its security teams. A $10,000 bug bounty award was also given to Melamed. The vulnerability is similar to a vulnerability discovered by another researcher around the same time. Facebook has since fixed the flaw and paid Melamed a $10k bug bounty.”]
