An unfiltered order could lead to a surprise dish that was never intended! If exploited, an attacker could inject harmful scripts that run in the browsers of anyone viewing the compromised page. This means they could steal cookies, capture sensitive data, or impersonate users—talk about an absolute nightmare!
