(Meredith) -- A flaw in Facebook's messenger app for kids allowed thousands of users to enter group chats with unapproved strangers, The Verge reports.
Facebook's Messenger Kids app was established in 2017 and allows children ages 6-12 to chat with users who are pre-approved by their parents.
However, an error on the app made it possible for children to enter group chats with friends-of-friends who were not approved by their parents.
Last week, Facebook sent out a notice to thousands of users, letting them know about the error.
Facebook said the flaw only affected a small number of group chats. It's unclear how long the flaw went unnoticed, but Facebook said it has fixed the issue.
