The attacker has stolen access tokens of the Facebook users and was able to log in each and every account, also access photos, messages, posts and contacts. As a precautionary step, the feature that was vulnerable was removed from Facebook temporarily and the access tokens that were stolen by the attacker was invalidated so the attacker will not be able to login to the users account again. Facebook has also logged out another 40 million Facebook accounts suspecting that these users might have been affected.
