⚠️ A simple email input on your Daily Expense Tracker can lead to a SQL injection nightmare! Imagine a thief casually walking through the front door because you left it unlocked! This SQL injection vulnerability is like a careless waiter who serves your order without checking the menu — allowing a customer to request anything from the kitchen without permission.

Imagine losing all your financial records and personal information to someone who simply asked for it — absolutely devastating!
