## Affected

- haibasoft Thanh Toán Quét Mã QR Code Tự Động – MoMo, ViettelPay, VNPay và 40 ngân hàng Việt Nam: through 2.0.1

## Description

The Thanh Toán Quét Mã QR Code Tự Động – MoMo, ViettelPay, VNPay và 40 ngân hàng Việt Nam plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 2.0.1 due to incorrect use of the wp_kses_allowed_html function, which allows the 'onclick' attribute for certain HTML elements without sufficient restriction or context validation. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
