Technical details
An improper authorization vulnerability exists in the `save_users` function within `classes/Users.php` of SourceCodester Multi-Vendor Online Grocery Management System 1.0. The endpoint lacks session validation or authentication checks at the file level. Furthermore, the function uses PHP's `extract($_POST)` to dynamically build SQL queries without filtering sensitive columns like 'type'. A remote, unauthenticated attacker can send a crafted POST request including `type=1` to register a new account with full administrative privileges. This can be further chained with other vulnerabilities to achieve remote code execution.
