The MyBB team have released a security patch which fixes 3 security vulnerabilities in the current 1.4.x forum software. Two of these problems are low risk, either requiring admin permissions or do not cause any harm to your board. The other problem however is a high risk SQL injection vulnerability and therefore you should update your board immediately.
You can download the full MyBB 1.4.9 package from the MyBB Download section now. Alternatively you can download and manually apply the required file edits (there are only 7 small edits to make). As always, be sure to make a backup of your files and database.
As a security release no template changes were made in this release so all current themes will continue to provide full functionality for your board.
More information about this release can be found on the MyBB blog
