WordPress Simple PayPal Shopping Cart <= 5.1.2 - Unauthenticated Product Price Manipulation

Published Apr 23, 2025 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description
The WordPress Simple Shopping Cart plugin for WordPress is vulnerable to product price manipulation in all versions up to, and including, 5.1.2. This is due to a logic flaw involving the inconsistent use of parameters during the cart addition process. The plugin uses the parameter 'product_tmp_two' for computing a security hash against price tampering while using 'wspsc_product' to display the product, allowing an unauthenticated attacker to substitute details from a cheaper product and bypass payment for a more expensive item.
