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.

⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.

Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

  1. Ask the user to state the exact target URL, IP, account, or resource.
  2. Ask the user to confirm written authorization and the permitted scope.
  3. Show the exact command(s) and explain their expected effect.
  4. Wait for explicit confirmation in the current conversation.

Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

AUTHORIZED USE ONLY: Use this skill only for authorized security assessments, defensive validation, or controlled educational environments.
