IDOR Vulnerability Testing

What problem does it solve?

This skill provides structured guidance for detecting insecure direct object reference vulnerabilities, testing access controls, and remediating issues in web applications with proper authorization.

Core Features & Use Cases

• Systematic IDOR testing: Identify direct references to user data and static files, enumerate IDs, and verify access controls.
• Detection to remediation: Document findings and propose fixes to enforce ownership checks and indirect references.
• Use Case: Imagine testing an e-commerce app; you verify that changing a product or user ID in requests does not expose other users' data, and you report the access control bypass weaknesses with clear remediation steps.

Quick Start

1. Obtain explicit authorization to test the target application.
2. Gather two or more test user accounts and the target URLs or APIs.
3. Use intercepting proxies (e.g., Burp Suite) to capture and manipulate requests, then observe responses for data ownership deviations.
4. Document findings with evidence, classify impact, and propose remediation steps.
