In the Ban List plugin 1.0 for MyBB, any forum user with mod privileges can ban users and input an XSS payload into the ban reason, which is executed on the bans.php page.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
