IVPAY Payments Plugin SQL Injection and Authentication Bypass

Executive Summary

The IVPAY payments WordPress plugin up to version 1.0.8 has a flaw where it does not properly sanitize the 'payment_id' parameter in its payment callback function. This allows unauthenticated attackers to inject malicious SQL code into database queries. Additionally, the plugin incorrectly accepts an empty API key as valid authentication, letting attackers bypass security controls entirely.
