Code injection

Code injection is a way of putting something into a program that was not supposed to be there. It's like hiding a toy in someone's backpack without them knowing. But, instead of hiding a toy, we add our own code to a computer program. This can be done in many different ways, but some common ways are using vulnerabilities or errors in the program, or tricking the program into thinking our code is part of it.

Once the code is injected, it can do things. It might change the way the program works or even take over the whole computer. This is kinda like the toy in the backpack distracting the person using the backpack. It can also be bad and dangerous, like a bad person hiding in the backpack and doing bad things.

Code injection can be used for many things. Good people might use it to fix errors or add new features to programs. Bad people might use it to steal information, cause damage, or take control of things they shouldn't. So, it is very important to be careful and protect against code injection!
