Categorify <= 1.0.7.4 - Missing Authorization in categorifyAjaxUpdateFolderPosition

The Categorify plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the categorifyAjaxUpdateFolderPosition in all versions up to, and including, 1.0.7.4. This makes it possible for authenticated attackers, with subscriber-level access and above, to update the folder position of categories as well as update the metadata of other taxonomies.
