Wisdom is not a product of schooling but of the lifelong attempt to acquire it. ― Albert Einstein
What is SQL Injection
SQL is how your application communicates with you database, SQL injection is a web security vulnerability that allows an attacker to interfere with the queries that an application makes to its database. It generally allows an attacker to view data that they are usually not able to retrieve. This might include data belonging to other users, or any data that the application is able to access. In many cases, an attacker can modify or delete this data, causing persistent changes to the application’s content or behavior.
