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.

  1. Did anyone fix the LOWER sql search on usernames logging in yet? It means it doesn’t use the index and causes 100% cpu issues on larger sites when spam bots try to login. There is no need for that query to be case sensitive as far as I’m aware

  3. I applied the changed files to a 1.6.11 installation, but got an error saying that the board needed to be updated when trying to visit my forum or the ACP. After running the upgrade script (which was announced as not being necessary), I no longer get that error.

  4. Ugh, I was using 1.6.11 and used the changed files package, but MyBB still thinks it’s 1.6.11. The admin control panel keeps telling me I need to upgrade.

      • I was afraid someone would say that. Just to be sure, I unpacked the files to the proper directory for a third and fourth time. MyBB still indicates that it is 1.6.11 and the control panel indicates that there is still a newer version.
