This walks you through finding and exploiting Insecure Direct Object Reference vulnerabilities where applications expose database IDs or file paths that let you access other users' data. You get systematic testing methods for manipulating parameters in URLs and request bodies, using Burp Suite's Intruder for enumeration, and identifying common vulnerable patterns like incrementing invoice IDs or receipt filenames. It covers both horizontal privilege escalation (user to user) and includes practical checklists for what to test and how to interpret responses. The workflow assumes you have legitimate authorization and at least two test accounts to verify cross-user access. Good for penetration testers who need a structured approach beyond just changing an ID and hoping it works.
