# Swagger / OpenAPI Exposed in Production

## Overview
API documentation endpoints expose:
- Complete API schema including undocumented endpoints
- Authentication mechanisms and expected formats
- Example payloads that can be used for fuzzing
- Internal models and data structures

While useful in development, public Swagger in production gives attackers a full roadmap of the API.

## Remediation
- Restrict Swagger UI to internal networks or authenticated users
- Disable Swagger in production builds
- Use `NODE_ENV=production` check or similar to conditionally serve docs
