## Summary

wePOS (Point Of Sale for WooCommerce) before version 2.0.3 lets a logged-in user with vendor-level access, such as Dokan vendor staff, mark orders they don't own as paid and completed through its payment processing endpoint. Doing so can trigger stock reduction and grant access to paid-order content without any real payment, and the attack is carried out remotely over the network with low-privilege login.

## Affected

## Description

wePOS (Point Of Sale for WooCommerce) before 2.0.3 contains a missing authorization vulnerability in the wepos/v1/payment/process REST route that allows authenticated vendor-level users to mark arbitrary orders as paid and completed by supplying another order's ID. Attackers with only the publish_shop_orders capability (such as Dokan vendor staff) can invoke the payment processing endpoint with an order ID they do not own to trigger the order completion lifecycle, including stock reduction and granting of paid-order access, without making any real payment.
