Facebook’s Messenger Kids app had a breach allowing unapproved strangers to enter group chats with kids.
Facebook has been closing down those group chats and alerting users without yet making any public statements disclosing the issue.
The alert which Facebook sent out is as below:
Hi [PARENT],
We found a technical error that allowed [CHILD]’s friend [FRIEND] to create a group chat with [CHILD] and one or more of [FRIEND]’s parent-approved friends. We want you to know that we’ve turned off this group chat and are making sure that group chats like this won’t be allowed in the future. If you have questions about Messenger Kids and online safety, please visit our Help Center and Messenger Kids parental controls. We’d also appreciate your feedback.
The cause of the breach was a bug which arose due to complexities of the group chat feature.
