Persian Elementor (المنتور فارسی) <= 2.8.1 - Unauthenticated Price Manipulation via ZarinPal Widget

The Persian Elementor (المنتور فارسی) plugin for WordPress is vulnerable to Price Manipulation in all versions up to, and including, 2.8.1. This is due to the plugin trusting a user-supplied payment amount without server-side validation against the configured ZarinPal widget price. This makes it possible for unauthenticated attackers to submit arbitrary payment amounts to the ZarinPal gateway via the 'amount' parameter.
