# API Reference — Performing GraphQL Depth Limit Attack
|
|
|
|
## Libraries Used
|
|
- **requests**: Send GraphQL queries with depth/width/batch payloads
|
|
- **time**: Measure response latency for resource exhaustion detection
|
|
|
|
## CLI Interface
|
|
```
|
|
python agent.py depth --url <endpoint> [--max-depth 20] [--auth-header "Bearer token"]
|
|
python agent.py circular --url <endpoint> --type-a User --field-a posts --type-b Post --field-b author [--depth 10]
|
|
python agent.py batch --url <endpoint> [--count 50]
|
|
python agent.py width --url <endpoint> [--width 50] [--depth 5]
|
|
```
|
|
|
|
## Core Functions
|
|
|
|
### `build_nested_query(field_name, depth, leaf)` — Construct nested query payload
|
|
Generates progressively deeper GraphQL queries for depth limit probing.
|
|
|
|
### `test_depth_limit(url, max_depth, headers)` — Probe depth enforcement
|
|
Sends queries at increasing depth (1 to max_depth). Classifies severity:
|
|
HIGH (>=15 allowed), MEDIUM (>=8), LOW (<8).
|
|
|
|
### `test_circular_query(url, type_a, field_a, type_b, field_b, depth)` — Test circular references
|
|
Builds alternating A.field_a -> B.field_b chains to test circular query handling.
|
|
|
|
### `test_batch_query(url, count, headers)` — Test batch query bypass
|
|
Sends array of N queries to check if batching bypasses per-query depth limits.
|
|
|
|
### `test_resource_exhaustion(url, width, depth, headers)` — Test wide+deep queries
|
|
Combines field width (aliases) with nesting depth. Flags SLOW_RESPONSE if >5s.
|
|
|
|
## Severity Classification
|
|
- **HIGH**: No depth limit or limit >= 15 levels
|
|
- **MEDIUM**: Depth limit 8-14 or batch queries accepted
|
|
- **LOW**: Depth limit < 8 with proper enforcement
|
|
|
|
## Dependencies
|
|
```
|
|
pip install requests
|
|
```
