Authenticated SQL injection via unescaped proid parameter

Published Sep 6, 2021 · Updated Aug 3, 2024

SQL injection in the Alipay/Tenpay/PayPal WordPress plugin through 3.7.2 allows remote authenticated users to execute SQL via a crafted proid GET parameter. The administrative request inserts proid directly into an unquoted SQL statement without sanitization, escaping, or validation. Access requires authenticated WordPress administrative privileges; successful exploitation can read or modify database contents and affect confidentiality, integrity, and availability.
