See how missing ownership checks allow users to access, modify, or delete data belonging to other people simply by changing an ID in the URL.
Imagine a cloakroom where the attendant confirms you have a ticket, but then hands you whatever coat matches the number you say out loud, without checking if it's actually your ticket number. In APIs, BOLA (formerly known as IDOR) happens when an endpoint exposes an object identifier (like /api/invoices/9876) and the server verifies the user is logged in, but completely fails to verify if the user has permission to interact with invoice 9876.
Real attacks use automation. Attackers don't just peek at one record; they write scripts to iterate through sequential IDs (9877, 9878, 9879) or sweep through millions of leaked UUIDs, systematically draining a competitor's database or modifying other users' account settings in bulk.
