What is SQL Injection?

A code injection attack that allows attackers to interfere with the queries that an application makes to its database.

Expanded Explanation

SQL Injection occurs when malicious SQL statements are inserted into a form input or URL parameter and executed by the database server. This can allow attackers to read or modify sensitive data, bypass authentication, or even execute administrative operations. Preventing SQLi involves using parameterized queries, input validation, and web application firewalls.
