# SKILL: IDOR / Broken Object Level Authorization — Expert Attack Playbook

> **AI LOAD INSTRUCTION**: IDOR is the #1 bug bounty finding. This skill covers non-obvious IDOR surfaces, all attack vectors (not just URL params), A-B testing methodology, BOLA vs BFLA distinction, chaining IDOR to higher impact, and what testers repeatedly miss.

---

## 1. IDOR vs BOLA vs BFLA

| Term | Meaning | Impact |
|---|---|---|
| IDOR | Insecure Direct Object Reference | Read/modify other users' data |
| BOLA | Broken Object Level Authorization (OWASP API Top 10 A1) | Same as IDOR, API terminology |
| BFLA | Broken Function Level Authorization | Low-priv user accesses HIGH-PRIV functions (e.g., admin endpoints) |
