Steal sensitive user data, credit card information, or passwords.

If changing pk=1 to pk=2 allows a user to view another customer’s private invoice, medical record, or account details without logging in as that user, the system is vulnerable to IDOR. How Threat Actors Exploit This Footprint
Attackers rely on predictable URL patterns. Instead of using ?pk=1&id=1 , use strategies to hide your parameters:
In the world of search engine optimization and web research, the inurl: operator is a powerful filtering tool. It restricts search results to only those pages where your specified keyword appears in the web address itself. However, in the hands of security professionals, this simple search becomes a Google Dork —a technique used to identify potentially vulnerable web applications.
