Facebook bug leaked private photos of millions of users to app developers




A bug in Facebook has made private photos of millions of users available to hundreds of app developers for twelve days. The leak dates from September and has since been remedied. This reports the website Recode.net.

Facebook has publicized the bug in the Photo api Friday night in a blog post . According to the company, it may have affected 6.8 million users and covers 1500 apps from 876 developers. This mainly concerns people who use Facebook Login and who have granted third-party apps access to their photo library. In those circumstances, certain applications between 13 and 25 September could have access to ‘a larger number of photos than usual’, according to Facebook’s statement.

“When a Facebook user gives an app access to his photos, that app usually only gets access to the images that appear on his timeline, but this bug allowed developers to potentially view other photos, such as images on Marketplace or Facebook Stories”, the statement continues. The same applies to photos that were uploaded, but that were never actually shared, for example because the connection at that time was too bad.

Facebook users who have been the victim of the bug will receive a notification with a link to the social network site’s Help Center. There they can easily request which apps may have had access to their snaps. For Facebook it is the umpteenth privacy blunder of the end of the year. Earlier in 2018, the service went wrong with the accidental ‘unblocking’ of blocked contacts, there was a bug that adapted users’ sub-options unasked, and hackers gained access to the private data of more than fifty million users. In addition, Facebook was discredited in March by a data breach about Cambridge Analytica , after the data of millions of Facebook users were possibly manipulated for the Trump campaign in 2016.
