Vulnerability Overview
The Thank You Page Customizer for WooCommerce – Increase Your Sales plugin for WordPress is vulnerable to unauthorized execution of shortcodes due to a missing capability check on the get_text_editor_content() function in all versions up to, and including, 1.1.2. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute arbitrary shortcodes.
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
Thanko Thank You Page Customizer for WooCommerce <= 1.1.2 carries this weakness at get_text_editor_content(), 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 Thanko Thank You Page Customizer for WooCommerce the fix is 1.1.3: builds <= 1.1.2 are affected, anything from 1.1.3 onward is not.
Remediation
Update to version 1.1.3, 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: Thanko Thank You Page Customizer for WooCommerce 1.1.3 closes this, and updating the plugin is the step that ends it.
