Advisory

Source description from Wordfence Intelligence, credited to berke bodur.

The WebToffee Gift Cards for WooCommerce plugin for WordPress is vulnerable to Unauthenticated Gift Card Amount Manipulation in all versions up to, and including, 1.3.0. This is due to missing server-side validation of the user-supplied `wt_credit_amount` parameter against the product's configured denominations before it was applied as the cart item price and store-credit coupon value. This makes it possible for unauthenticated attackers to manipulate the gift card purchase price by submitting an arbitrary or negative amount for the `wt_credit_amount` parameter, bypassing configured denominations to obtain gift cards and store credits without paying the correct price.
