Technical details

A broken access control vulnerability exists in SourceCodester Indian Invoicing System 1.0 due to insufficient role validation. While the application checks for a valid user session, it fails to verify if the authenticated user possesses administrative privileges before granting access to sensitive management pages. An attacker with low-privileged credentials can bypass intended navigation restrictions to access endpoints like /home.php, /category.php, /state.php, and /cpyprofile.php. This allows for unauthorized Create, Read, Update, and Delete (CRUD) operations on core business data. The vulnerability is currently unpatched.
