The issue may have affected as many as 6.8 million users.
Facebook disclosed another software bug on Friday that may have exposed some users’ private photos to app developers without their permission. The bug, which was live for 12 days in September, may have impacted as many as 6.8 million users.
Facebook says the bug impacted hundreds of apps that let users create accounts and sign in using their Facebook login information. The software bug gave hundreds of developers access to a broader range of Facebook photos than are usually allowed.
