Broken Access Control

Overview

Discover common authorization flaws, test IDORs and missing access checks, and implement strong, centralized authorization.

Learning Outcomes

• Identify IDOR and path traversal authorization gaps
• Distinguish horizontal vs vertical privilege escalation
• Apply role- and attribute-based access control
• Enforce server-side checks consistently
• Design deny-by-default access patterns

Hands-on Labs

Exploit IDORs in a safe app, add missing checks, and validate fixes with tests and tooling.

Hardening

Centralize authorization, minimize object references, and log access denials with context.
