Description
The Payment forms, Buy now buttons, and Invoicing System | GetPaid plugin for WordPress is vulnerable to price manipulation in versions 2.0.0 to, and including, 2.8.62, due to insufficient validation of item quantities in payment form submissions and buy-now item lists, which accepted negative values. This makes it possible for unauthenticated attackers to lower the total of a checkout and pay less for other items in the same order.
