CVE-2026-84906 Details
Description
The Eventin WordPress plugin before 4.1.24 does not verify that a completed payment corresponds to the order it is applied to, confirming only that the payment gateway reports the transaction as successful, not its amount, currency, or which order it belongs to, allowing unauthenticated visitors to mark unpaid orders of any value as paid by replaying the transaction of a single genuine low-value payment.
A vulnerability in the Eventin WordPress plugin, affecting versions prior to 4.1.24, allows unauthenticated users to manipulate payment statuses of orders. The plugin fails to properly verify that a payment corresponds to the correct order, only checking if the payment gateway indicates a successful transaction. This oversight enables users to mark unpaid orders as paid by replaying the transaction of a single legitimate low-value payment.
Users are advised to update the Eventin WordPress plugin to version 4.1.24 or later.
