公告说明

Summary

The Order::setPaymentAmount() method accepts any float value without enforcing a minimum positive amount. The PaymentsController casts the user-supplied 'paymentAmount' parameter directly to float with no lower-bound check.

Details

When the store has 'Allow Partial Payment on Checkout' enabled, a user can submit a payment amount of $0.00 or even a negative value, potentially marking orders as paid without a valid transaction.

PoC

Complete instructions, including specific configuration details, to reproduce the vulnerability. <img width="606" height="144" alt="image" src="https://github.com/user-attachments/assets/a04a6de2-7c5f-4837-aed6-58756e246b80" />

Impact

On stores with partial payment enabled, a customer may be able to set an arbitrarily small payment amount. Gateway behavior varies — some will process $0.00 transactions, effectively giving free order fulfillment.
