SQL injection is a type of cyber attack that targets the security vulnerabilities present in web applications. It occurs when malicious SQL (Structured Query Language) code is inserted into input fields or parameters, allowing attackers to manipulate the SQL queries executed by the application's database. This exploitation can lead to unauthorized access to sensitive data, unauthorized manipulation of data, or even the complete takeover of the affected system. By injecting malicious SQL commands, attackers can bypass authentication, extract data, modify databases, or execute administrative operations.
