Reporting MyBB security vulnerabilities

If you think you’ve found a vulnerability in MyBB, we advise you not to publicly post it on these forums or publicly release information about it elsewhere until we’ve had time to prepare and release a patch.

As always, you can send through security related messages on the MyBB website from the Contact Us page or in our Private Inquiries forum – where you can start a new thread that only you and the MyBB Team can see.

Thanks,

MyBB Team
