Cross-Site Request Forgery in Dynamic Input Field Generator Using HTML CSS and PHP

Executive Summary

This is a Cross-Site Request Forgery (CSRF) vulnerability in the Dynamic Input Field Generator web application. The flaw allows attackers to trick users into submitting unauthorized requests by hosting a malicious page that auto-submits forged requests to the vulnerable application. The attack exploits the lack of CSRF protection in the submit.php file, which processes POST requests without validating their origin or authenticity.
