Unauthorized Data Modification in WooCommerce Product Specifications

Publication date: 2026-06-27

Last updated on: 2026-06-27

Assigner: Wordfence

Description
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.

Executive Summary

The Product Specifications for WooCommerce plugin for WordPress has a vulnerability in versions up to and including 0.8.9 that allows unauthorized modification, creation, and deletion of data.

This happens because the plugin is missing capability checks and nonce verification in certain methods (__invoke() methods of the AttributeGroupController and AttributeController classes) tied to AJAX actions.

As a result, authenticated users with Subscriber-level access or higher can create, edit, and delete arbitrary product specification groups and attributes, which are taxonomy terms in the 'spec-group' and attribute taxonomies.

This vulnerability can allow attackers with low-level authenticated access to corrupt business data by creating, modifying, or deleting product specification groups and attributes.

Such unauthorized changes can impact the frontend display of the site, potentially misleading customers or disrupting normal business operations.

Compliance Impact

The vulnerability allows authenticated attackers with Subscriber-level access and above to create, edit, and delete arbitrary product specification groups and attributes, potentially corrupting business data and impacting the site's frontend display.
