# NestJS Security Hunting
Hunt NestJS-specific vulnerabilities in guard bypass via decorator stack gaps, Reflector metadata mismatches between global/controller/method guards, ValidationPipe whitelist and transform exploits, and microservice transport authentication drift. NestJS's architectural patterns — decorators, dependency injection, module system, multi-transport support — create unique attack surface across HTTP, WebSocket, and RPC transports.
## When to Use
- Target uses NestJS (indicated by `x-powered-by: NestJS` or TypeScript decorator patterns in error messages).
- GraphQL endpoints exist alongside REST API.
- Microservice transports (TCP, Redis, NATS, MQTT, gRPC) are configured.
- Swagger/OpenAPI docs are exposed at `/api` or `/api-json`.
- CRUD endpoints follow predictable NestJS naming conventions.
## Quick Detection
