A bug in the code of a Facebook update rolled out last week accidentally made it possible to see which accounts were responsible for posts to Facebook Pages, including those of celebrities and politicians, for a period of several hours.
“All it took to exploit the bug was opening a target page and checking the edit history of a post. Facebook mistakenly displayed the account or accounts that made edits to each post, rather than just the edits themselves,” explained Wired.
Facebook was quick to post a fix, thanks to a security reacher who alerted them to the big. “We quickly fixed an issue where someone could see who edited or published a post on behalf of a Page when looking at its edit history,” Facebook said in a statement.
