Elias spent the night reading through the archives. He saw the risk: if he found this so easily, someone else would too, and they might delete it all for sport. $query = "SELECT * FROM users WHERE id = "
Even if SQL injection isn’t possible (e.g., the database is secure), the URL structure reveals an vulnerability. This means the application uses direct references to internal objects (like a user pk ), but fails to check if the logged-in user is authorized to access that object. He saw the risk: if he found this
What does a fragment like this tell us? It hints at structure. URLs are not random; they are maps, often encoding parameters that control content, identity, or behavior.

This is the single most effective defense. Never concatenate user input directly into a SQL string.
