CVE-2023-28843Network attack vector

Unauthenticated database compromise via unsanitized receiver email

Published Mar 31, 2023 · Updated Feb 11, 2025

SQL injection in PayPal Official Module 3.12.0 through 3.16.3 for PrestaShop 1.6 allows remote attackers to read or alter store data. The ipn.php notification path passes the receiver_email GET or POST value to Db::getInstance()->insert without pSQL neutralization, allowing SQL syntax to alter the database operation. No authentication or user interaction is required; a reachable affected store can expose technical and personal data, grant administrative access, or lose linked-store data.
