Vulnerability Overview

The Product Feed PRO for WooCommerce WordPress plugin before 11.0.7 does not have authorization and CSRF check in some of its AJAX actions, allowing any authenticated users to call then, which could lead to Stored Cross-Site Scripting issue (which will be triggered in the admin dashboard) due to the lack of escaping.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in Product Feed PRO for WooCommerce by AdTribes < 11.0.7 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Product Feed PRO for WooCommerce by AdTribes the fix is 11.0.7: builds < 11.0.7 are affected, anything from 11.0.7 onward is not.

Remediation

Update to version 11.0.7, or a newer patched version
