# IDOR Hunting Playbook

IDOR is the #1 source of bug bounty payouts because it's simple,
ubiquitous, and scanners can't find it (authorization is business
logic). Every endpoint that takes an object ID is a candidate.

## 1. Sources

- URL path segments: `/api/users/123/invoices/456`
- Query string: `?user_id=123`
- JSON body fields: `{"orderId": 123}`
- Headers used as auth scope: `X-Tenant-ID`, `X-Customer-Id`
- JWT claims that downstream handlers *trust*: `sub`, `tenant`, `role`
- WebSocket subscription filters
