Code Injection

Code injection is a type of security vulnerability where an attacker inserts malicious code into a program, exploiting weaknesses in how that program processes input. This can allow the attacker to manipulate the program's behavior, access sensitive data, or execute harmful actions. For example, if a website doesn't properly validate user input, someone could enter harmful code that gets run by the website's server. To prevent this, developers must sanitize and validate all inputs, ensuring that only safe data is processed. Proper coding practices and security measures are essential to protect against such attacks.
