Consider you are a security tester for a new web application. You identify a potential vulnerability that allows for data injection into the system. What type of vulnerability have you likely found?

SQL Injection is a type of vulnerability that allows attackers to inject malicious SQL code into an application, thereby gaining unauthorized access to a database and fetching/altering its contents. While XSS and Buffer Overflows are vulnerabilities, they aren't typically associated with direct data injection into databases.
