It has come to our attention that a problem exists with the code used to run paid subscriptions when using Authorize.net as the payment manager.
The problem is minor and difficult to exploit, but we have updated the vBulletin 3.0.3 package in the members' area with updated code.
If you are already running vBulletin 3.0.3, you need only download the authorize.php file attached to this message and upload it to your 'subscriptions' directory on your server.
If you are running a version of vBulletin 3 earlier than 3.0.3, we recommend that you upgrade to the version of 3.0.3 available in the members area.
If you are not using paid subscriptions with Authorize.net, you may simply delete the subscriptions/authorize.php file completely.
