Imagine a restaurant that allows deliveries from any random supplier without checking the order — one slip-up and you might end up with spoiled ingredients in your kitchen! The issue arises from a lack of proper validation on uploaded files, allowing attackers to upload files of dangerous types, such as scripts, that can be executed on the server. This effectively opens the door wide for remote code execution without any user authentication required!
