Practical SQL Injection Exploitation Cheat Sheet

SQL Injection (SQLi) remains one of the most dangerous vulnerabilities in web applications, allowing attackers to manipulate databases, extract sensitive data, and even gain remote access. This cheat sheet focuses on real-world SQLi exploitation with hands-on examples, bypassing security filters, and using tools like Burp Suite and SQLMap.

Before executing SQL injection attacks, set up a safe environment:
