What it tells the agent

The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

# 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)
