A Facebook bug exposed the photos of 6.8 million people, that they had chosen to not share publicly on the social media site.
Facebook said that photos that were not shared could have been accessed. Facebook said that photos that weren’t shared on its platform could be accessed because the platform stores a copy of photos that users choose not to share on their profile after uploading.
Facebook said the bug affected a 12 day window Sept. 13 to Sept. 25 and gave access to 1,500 apps built by more than 800 developers. Facebook said they became aware of the bug and fixed it on Sept. 25.
