Description
The Payment forms, Buy now buttons, and Invoicing System | GetPaid plugin for WordPress is vulnerable to Insecure Direct Object Reference via the 'invoice_id' payment form parameter in all versions up to, and including, 2.8.54, due to a missing check on whether the submitter owns the referenced invoice or supplied its key. This makes it possible for unauthenticated attackers to submit a payment form checkout against any other user's unpaid invoice, overwriting its billing email, items, fees, discounts, address and payment gateway.
