Facebook bug exposed photos from up to 6.8 million users using third-party apps, the company disclosed Friday. The exposed photos include those that users never finished sharing to the site, Facebook said.

The disclosure is one of several privacy breaches the company has shared over the past year. In March, reports from the New York Times and the Guardian shed light on how Cambridge Analytica used data on Facebook users to influence the 2016 U.S. presidential election. In September, it announced a security breach that affected up to 50 million users and sent its stock price plunging more than 2.5 percent.
