Smart Online Order for Clover <= 1.5.6 - Missing Authorization to Authenticated (Subscriber+) Plugin Data Update

The Smart Online Order for Clover plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on several functions in all versions up to, and including, 1.5.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update product and category descriptions, category titles and images, and sort order.
