This guide provides a comprehensive methodology for identifying and exploiting Insecure Direct Object Reference (IDOR) vulnerabilities in web applications and APIs. It teaches testers how to systematically manipulate object identifiers (such as numerical IDs, UUIDs, or slugs) within API requests and URLs. Techniques involve using advanced tools like Burp Suite's Authorize extension to test object-level access control, validating both horizontal (same privilege) and vertical (different privilege) access restrictions during authorized penetration tests or bug bounty engagements.
