SQL injection

SQL injection is one of those sneaky security problems that can cause serious damage if overlooked. Imagine someone finding a way to slip unauthorized commands into your database through everyday features like login forms or search boxes. Instead of just entering their username, they might add extra database commands that could leak sensitive data or mess with your database. It's like someone turning a simple question into a harmful command. Fortunately, preventing SQL injection isn't rocket science - developers can use techniques like prepared statements (which separate code from user input) or input validation (which checks if user input looks suspicious). It's one of those security basics that every developer should know about, kind of like remembering to lock your front door before leaving home.
