Facebook has fixed a flaw that let hackers delete Facebook friends without permission. The flaw was reported Wednesday by a student at Marist College in Poughkeepsie, New York. The bug was a variation of an earlier vulnerability that Facebook learned about last week. Facebook has struggled this week to fix these bugs, which are called cross-site request forgery flaws. They exist because of relatively simple Web programming mistakes in the Web site’s code, and security researchers have criticized Facebook for not fixing them more quickly.”]
