(Reuters) — Facebook Inc. said on Friday it has discovered a bug that may have affected up to 6.8 million people who used the Facebook login to grant permission to third-party apps to access photos.
The company said in a blog that the problem has been fixed but that it may have affected up to 1,500 apps built by 876 developers.
Facebook said some third-party apps may have gained access to a broader set of photos than usual for 12 days between Sept. 13 to Sept. 25.
The bug is the latest in a string of privacy problems the tech giant disclosed this year, including the massive Cambridge Analytica Ltd. data scandal in April and a data breach of nearly 30 million accounts in October.
Facebook shares were down 1.3% at $143.07 in early trading on Friday. The Nasdaq composite index fell 0.9%.
(Reuters) — Facebook Inc.'s lead regulator in the European Union, the Irish Data Protection Commissioner, on Wednesday began an investigation into a massive cyber attack on the social networking site disclosed by the company last week.
