exploiting-idor-vulnerabilities

separate

Identifies and exploits Insecure Direct Object Reference (IDOR) vulnerabilities by manipulating object identifiers (numeric IDs, UUIDs, slugs) in API requests and URLs, using Burp Suite proxy history, Intruder, and the Authorize extension to test object-level authorization across sessions. Use during authorized penetration tests or bug bounty work to validate that CRUD endpoints and multi-tenant applications enforce per-object access control.

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
