What the vulnerability does
01Description
The Product Specifications for WooCommerce plugin for WordPress is vulnerable to unauthorized modification, creation, and deletion of data in versions up to and including 0.8.9. This is due to a missing capability check and missing nonce verification in the __invoke() methods of the AttributeGroupController and AttributeController classes, which are bound to the 'dwps_modify_groups' and 'dwps_modify_attributes' AJAX actions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create, edit, and delete arbitrary product specification groups and attributes (taxonomy terms in the 'spec-group' and attribute taxonomies), corrupting business data and impacting the site's frontend display.
