How TheSiteFuse checks "API endpoint security"

This check tests common API paths (/api/, /api/v1/, /graphql) without authentication to see if data is returned. An API that returns data without any valid token or session potentially exposes sensitive information to anyone. A 401 or 403 response indicates authentication is working correctly.

Real-world impact of "API endpoint security"

Unprotected APIs are often the cause of massive data breaches. A route that returns a user list, orders, or personal data without authentication is a critical flaw. It's not always intentional — sometimes the developer forgets to protect a test or staging endpoint.
