Description

The SureForms WordPress plugin before 2.11.1 does not properly validate the payment amount on forms that use a dynamically-sourced (variable/hidden) payment amount, allowing unauthenticated users to underpay for the configured product or subscription. Forms using a fixed configured price are not affected.
