⚡ An improper handling of user input lets attackers slip in their own JavaScript — a recipe for disaster if left unchecked! This flaw is like a restaurant that forgets to read customer orders, serving up whatever the last diner requested. When a malicious user inputs their own script, it’s as if they’ve snuck in a secret ingredient that ruins the meal for everyone! If exploited, an attacker could execute malicious scripts in the browsers of users accessing the Simple Finance Calculator, potentially compromising sensitive information or redirecting users to harmful sites. This could lead to harrowing data breaches or phishing attacks, and users might not even know it’s happening!
