Facebook users are being warned that a picture bug has been discovered which affected millions of users.
Up to 6.8million fans of the social networking site have been hit by the Facebook bug, the latest data breach to hit the internet giant in 2018.
The Facebook bug let third-party developers access photos on a user’s timeline as well as access to images posted in Stories and Marketplace.
The Facebook bug also let them see images people had uploaded but not posted to the site.
In a post online the social networking giant said: “When someone gives permission for an app to access their photos on Facebook, we usually only grant the app access to photos people share on their timeline.
“In this case, the bug potentially gave developers access to other photos, such as those shared on Marketplace or Facebook Stories.
“The bug also impacted photos that people uploaded to Facebook but chose not to post.
“For example, if someone uploads a photo to Facebook but doesn’t finish posting it – maybe because they’ve lost reception or walked into a meeting – we store a copy of that photo so the person has it when they come back to the app to complete their post.”
Facebook apologised for the picture bug and said that those who have been affected will receive a notification.
Facebook said: “We’re sorry this happened. Early next week we will be rolling out tools for app developers that will allow them to determine which people using their app might be impacted by this bug. We will be working with those developers to delete the photos from impacted users.
“We will also notify the people potentially impacted by this bug via an alert on Facebook. The notification will direct them to a Help Center link where they’ll be able to see if they’ve used any apps that were affected by the bug. (See example of user notification below)
“We are also recommending people log into any apps with which they have shared their Facebook photos to check which photos they have access to.”
Facebook said on their blog that the problem has been fixed but that it may have affected up to 1,500 apps built by 876 developers.
The bug is the latest in a string of issues the tech giant disclosed this year.
This includes the Cambridge Analytica data scandal in April and a data breach of nearly 30 million accounts in October.
