The RestroPress WordPress plugin before 3.4.6 does not validate a client-supplied item add-on price on the server side when items are added to or updated in the cart, allowing unauthenticated users to set an arbitrary price and place orders for an attacker-chosen total, down to and including zero.
AnalysisAI
Unauthenticated price tampering in the RestroPress WordPress plugin (versions before 3.4.6) lets any remote attacker alter the client-supplied add-on price when items are added to or updated in the cart, then place an order at an arbitrary - including zero - total. The flaw is a server-side validation failure affecting only sites that run RestroPress with online ordering/cart-and-checkout enabled and paid item add-ons configured; no credentials or user interaction are required and default configurations of the affected versions are exploitable. …
