At a glance
CVE-2026-11364 is a medium-severity Missing Authorization vulnerability in the Product Specifications for Woocommerce WordPress plugin, affecting versions <= 0.8.9. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 0.8.10; sites on affected versions should update now. Disclosed June 2026, reported by dyingman.
Vulnerability Overview
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.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-862: Missing Authorization
Product Specifications for Woocommerce <= 0.8.9 carries this weakness at dwps_modify_groups, and reaching it takes an account at Subscriber level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Product Specifications for Woocommerce the fix is 0.8.10: builds <= 0.8.9 are affected, anything from 0.8.10 onward is not.
Remediation
Update to version 0.8.10, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Product Specifications for Woocommerce 0.8.10 closes this, and updating the plugin is the step that ends it.
