San Francisco: About 6.8 million users may risk exposing their private photos to third-party apps, stated US social media network Facebook. The company on Friday stated the possibility that a bug may have affected more than 1,500 apps built by 876 developers.

Facebook pointed out the vulnerability of users’ unshared photos and stated that they may be exposed during a 12-day-period starting from September 13 to September 25, as per a report by Xinhua news agency. Promising to fix the breach, Facebook stated that new tools will be rolled out next week “for app developers that will allow them to determine which people using their app might be impacted by this bug.”

The bug enabled certain apps to view the pictures uploaded by Facebook users without prior permission. Last month, Facebook stated in a tweet, “Earlier today a bug in our server caused some people to have trouble accessing our apps. The issue has since been resolved – we’re back to 100% for everyone – and we’re sorry for the inconvenience.”

The disclosure of users’ private photos reinforces the failure of Facebook in taking adequate steps to ensure the protection of users’ privacy.

In the past years, the global social media giant has been grilled for mishandling user data, including its involvement in a privacy scandal in March when Cambridge Analytica, a British political consultancy firm, was accused of illegally accessing the data of more than 87 million Facebook users without their consent.

The private information of Facebook users was alleged to be used to influence the U.S. 2016 general elections in favour of President Donald Trump’s campaign.

Last month, Facebook announced that up to 50 million users could have their accounts controlled by hackers due to a security bug that its CEO Mark Zuckerberg called “very serious.”
