Facebook Unknowingly Shared User Info with Outside Developers

Facebook Inc. said it unknowingly gave outside developers access to private user information shared within some groups on its main social network, including the names and profile photos of people who were part of those groups. The company said that some third-party developers who used Facebook’s Groups API — a software program that allows information sharing between Facebook and outside developers — could see which users shared posts or left comments inside a group even though they weren’t supposed to have that level of detail.
