📚 Topic Summary
SQL Injection is a common web security vulnerability that allows attackers to interfere with the queries that an application makes to its database. Attackers exploit this vulnerability by inserting malicious SQL code into input fields, potentially gaining unauthorized access to sensitive data, modifying database records, or even executing administrative operations on the database server. Understanding SQL Injection is crucial for aspiring cybersecurity professionals to create secure web applications.
