The vulnerability stems from insufficient input sanitization of the \u003ccode\u003eproduct_id\u003c/code\u003e parameter, allowing injection of malicious SQL code. By leveraging time-based or content-based blind injection techniques, attackers can enumerate usernames, emails, and password reset codes from the \u003ccode\u003eoc_user\u003c/code\u003e table. This can lead to unauthorized access to user accounts and potential data breaches.
