Thanh toán chuyển khoản ngân hàng với VietQRPro từ Sổ Bán Hàng Security & Risk Analysis

The plugin "thanh-toan-chuyen-khoan-ngan-hang-voi-vietqr" v1.0.8 exhibits a mixed security posture. On the positive side, it demonstrates good practices with SQL queries being exclusively prepared and a high percentage of output being properly escaped. The absence of any known vulnerabilities in its history suggests a generally stable codebase. However, significant concerns arise from its attack surface. The presence of two AJAX handlers without authentication checks represents a direct pathway for potential unauthorized actions or information disclosure if these handlers are not adequately secured by other means. The taint analysis, while not reporting critical or high severity issues, did identify two flows with unsanitized paths, which could potentially lead to unexpected behavior or vulnerabilities if user-supplied data is not handled with extreme care within these flows. The complete lack of nonce checks and capability checks on these entry points further exacerbates the risk associated with the unprotected AJAX handlers.
