The Online Examination System Project 1.0 version is vulnerable to Cross-Site Request Forgery (CSRF) attacks. An attacker can craft a malicious link that, when clicked by an admin user, will delete a user account from the database without the admin's consent. The email of the user to be deleted is passed as a parameter in the URL, which can be manipulated by the attacker. This could result in a loss of data.

Online Examination System v1.0 is vulnerable to multiple Unauthenticated SQL Injection vulnerabilities. The 'email' parameter of the feed.php resource does not validate the characters received and they are sent unfiltered to the database.
