# SKILL: API Authorization and BOLA — Object Access, Function Access, and Mass Assignment
> **AI LOAD INSTRUCTION**: Use this skill when an API exposes object IDs, nested resources, or role-sensitive functions and you need a focused authorization test path: BOLA, BFLA, method abuse, and hidden field control.
## 1. CORE TEST LOOP
1. Create Account A and Account B.
2. As Account A, capture create, read, update, and delete flows.
3. Replay with Account B's token.
4. Test sibling endpoints, nested endpoints, and alternate HTTP verbs.
## 2. TEST SURFACES
| Surface | Example |
|---|---|
| object read | `/api/v1/orders/123` |
| nested object | `/api/v1/users/1/invoices/9` |
| admin or internal function | `/api/v1/admin/users` |
| update path | `PUT`, `PATCH`, `DELETE` variants |
| hidden JSON fields | `role`, `org`, `verified`, `tier` |
## 3. QUICK PAYLOADS
```json
{"role":"admin"}
{"isAdmin":true}
{"org":"target-company"}
{"verified":true}
```
## 4. WHAT TESTERS MISS
- object IDs in headers, cookies, GraphQL args, and nested objects
- alternate methods sharing the same route but weaker authz
- parent check present, child resource check missing
- admin docs revealing extra writable fields
## 5. NEXT ROUTING
- For JWT or token-layer abuse: [api auth and jwt abuse](../api-auth-and-jwt-abuse/SKILL.md)
- For GraphQL and hidden parameter discovery: [graphql and hidden parameters](../graphql-and-hidden-parameters/SKILL.md)
- For broader IDOR patterns outside APIs: [idor broken object authorization](../idor-broken-object-authorization/SKILL.md)Trust audit

Questions
What does the api-authorization-and-bola — yaklang/hack-skills skill do?
Helping AI Agent become an awesome practical hacker!
Is api-authorization-and-bola — yaklang/hack-skills safe to install?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.
What can api-authorization-and-bola — yaklang/hack-skills access on my machine?
The audit observed no filesystem, network or shell use at all in its source.
How current is this page?
