Security firm Imperva found a bug in May that allowed websites to read Facebook users and their friends’ private information. That means another website can access a logged-in Facebook user’s data through queries in code. To exploit the bug, a site can embed an IFRAME – a site within a site – to siphon off data from a user. Masas found this bug while researching a Chrome vulnerability that allowed hackers to steal Facebook users’ private info. He said that it also allowed accessing users’ friends’ data even if the information was kept visible only to friends.
