Summary
The Nexi XPay Build WordPress plugin from 7.2.2 through 7.6.2 does not correctly verify the security token on its payment notification route (CWE-345). It accepts notifications for orders that have no stored token, so an unauthenticated remote attacker can mark arbitrary orders as paid or mark genuinely paid orders as failed. A public exploit is linked in the references.

Description from the CNA
The Nexi XPay Build WordPress plugin through 7.6.2 does not correctly validate the security token on its payment notification route, accepting the request when the target order has no stored token, which allows unauthenticated attackers to mark arbitrary orders as paid, or to mark genuinely paid orders as failed.
