(Reuters) – Facebook Inc (FB.O) said on Friday it has discovered a bug that may have affected 6.8 million people who Facebook login to grant permission for third-party apps to access photos.
The company said in a blog that the problem is solved, but that it may have had an impact on up to 1,500 apps built by 876 developers.
Facebook said some third-party apps can have access to a wider set of pictures than normal for 12 days between Sept. 13 to Sept. 25.
The bug is the latest in a series of privacy issues that the tech-giant announced this year, including the massive Cambridge Analytica data scandal in April and a data breach of almost 30 million accounts in October.
Facebook shares fell 1.3 percent to $143.07 in the start of trading on Friday. The Nasdaq composite index .IXIC dropped 0.9 percent.
