What the vulnerability does
The SKT PayPal for WooCommerce plugin for WordPress is vulnerable to Payment Bypass in all versions up to, and including, 1.4. This is due to the plugin only enforcing client side controls instead of server-side controls when processing payments. This makes it possible for unauthenticated attackers to make confirmed purchases without actually paying for them.
Explanation of Vulnerability in Simple Terms
SKT PayPal for WooCommerce versions 1.4 and earlier contain a vulnerability that allows attackers to modify data without authentication. The flaw stems from insufficient input validation in the payment processing logic. No user interaction is required for exploitation. Site administrators should update to a version newer than 1.4 immediately.
What an attacker can do
Modify payment or order data without logging in to the site.
Potential impact on your site
Attackers can alter transaction records, order details, or payment information without authorization.
Conditions required to exploit
Network access to the site; no authentication or user interaction required.
