Advisory
Source description from Wordfence Intelligence, credited to Idan Malihi.
The Payment forms, Buy now buttons, and Invoicing System | GetPaid plugin for WordPress is vulnerable to Improper Input Validation in all versions up to, and including, 2.8.62. This is due to missing validation on the user-supplied quantity value in the process_item() function, allowing negative numbers to produce a negative line subtotal. This makes it possible for unauthenticated attackers to manipulate invoice totals to zero by submitting a negative item quantity on a public payment form, causing the invoice to be marked as paid without any actual payment being collected. A payment form with an item that allows customers to set quantities must be publicly accessible.
