Some vulnerabilities have been reported in MyBB, which can be exploited by malicious people to conduct SQL injection attacks.

1) Input passed to the "querystring" parameter in admin/adminfunctions.php and to the "setid", "expand", "title", and "sid2" parameters in admin/templates.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Some other parameters and scripts may also be affected.

Successful exploitation requires access to the admin section.

The vulnerabilities have been confirmed in version 1.1.1. Prior versions may also be affected.

2) Input passed to the "Email" field when registering for an account isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

The vulnerability has been reported in version 1.1.1. Prior versions may also be affected.

Solution
Update to version 1.1.2.
