sql-injection-search-endpoint
This case covers a Flask REST API that provides a user search endpoint with email-based filtering using SQLite. It focuses on an SQL injection issue caused by unsafe handling of user-supplied query parameters in a common API design pattern found in internal dashboards and administrative services. The case highlights how assumptions about trusted environments or limited exposure can introduce significant security risks, leading to unauthorized access to application data.
