# Exploiting IDOR Vulnerabilities

## When to Use

- During authorized penetration tests when testing access control on resource endpoints
- When APIs or web pages use predictable identifiers (numeric IDs, UUIDs, slugs) in URLs or request bodies
- For validating that object-level authorization is enforced across all CRUD operations
- When testing multi-tenant applications where users should only access their own data
- During bug bounty programs targeting broken access control vulnerabilities

## Prerequisites

- **Authorization**: Written penetration testing agreement for the target application
- **Burp Suite Professional**: With Authorize extension installed from BApp Store
