Facebook Inc. had a software bug for 10 days in May that set the audience for people’s posts to “public,” even if they had intended to share them just with friends, or a smaller audience.

The bug affected as many as 14 million people, the company said. Facebook will soon start individually informing the people who were affected by the bug.
