That drill trains you to attack the one identifier the application is most likely to check. The primary key in the URL path is where the framework&rsquo;s <code>@authorize</code> annotation lives, where the ORM scopes the query, where the review focused. It&rsquo;s the honeypot. You fuzz it, get <code>403</code>s, call the endpoint safe, and walk right past the bug.</p>
