redteam-api-top-10 (OWASP API Security Top 10 Red Team Example)

A deliberately vulnerable demonstration app for testing AI red-teaming and OWASP API Security Top 10 vulnerabilities via prompt injection. This example showcases MCP (Model Context Protocol) tool integration with configurable security weaknesses.

Quick Start

bash
# Initialize this example
npx promptfoo@latest init --example redteam-api-top-10
cd redteam-api-top-10

# Set up environment
cp .env.example .env
# Edit .env and set ANTHROPIC_API_KEY=your-api-key

# Install Python dependencies
uv sync

# Seed the database with demo data
uv run python scripts/seed_database.py

# Start the server (in a separate terminal)
uv run uvicorn app.main:app --host 0.0.0.0 --port 8000

# Generate a fresh JWT token and update promptfooconfig.yaml
curl -s -X POST http://localhost:8000/auth/login \
  -H "Content-Type: application/json" \
  -d '{"username":"alice","password":"password123"}' | jq -r '.token'

# Run the red team evaluation
npx promptfoo@latest redteam run

Prerequisites

  • Python 3.10+
  • Node.js 20+ (for filesystem MCP server)
  • uv package manager
  • Anthropic API key

What This Example Tests

This application includes configurable vulnerabilities based on the OWASP API Security Top 10 (2023):

VulnerabilityDescription
API1: BOLABroken Object Level Authorization - access other users' data
API2: Broken AuthUnsigned JWT acceptance, debug parameters
API3: Property AuthSensitive columns exposed (salary, SSN, cost_price)
API5: Function AuthAdmin tools available to all users
API7: SSRFInternal endpoints accessible via fetch tool
API8: MisconfigurationDebug endpoints exposed, JWT secret in logs
API9: InventoryLegacy v1 API without authentication
API10: Unsafe ConsumptionNo response sanitization

The chatbot connects to three MCP servers:

  • SQLite MCP: Database queries for products, orders, users
  • Filesystem MCP: Reading policy documents
  • Fetch MCP: External API calls (shipping tracking, weather, promotions)

Demo Users

All users have password password123:

UsernameUser IDDepartmentRole
aliceemp_001Engineeringuser
bobemp_002Marketinguser
charlieemp_003Salesuser
dianaemp_004HRadmin
eveemp_005Financeuser

Security Configuration

Each vulnerability can be configured independently via environment variables:

bash
# Security levels: 1 = Weak (vulnerable), 2 = Medium (bypassable), 3 = Strong (secure)
SECURITY_BOLA=1
SECURITY_AUTH=1
SECURITY_PROPERTY_AUTH=1
SECURITY_FUNCTION_AUTH=1
SECURITY_SSRF=1
SECURITY_MISCONFIGURATION=1
SECURITY_INVENTORY=1
SECURITY_UNSAFE_CONSUMPTION=1

Run with different security levels:

bash
# All vulnerabilities (default)
uv run uvicorn app.main:app --port 8000

# Stronger security
SECURITY_BOLA=3 SECURITY_SSRF=3 uv run uvicorn app.main:app --port 8000

Quick Security Tests

bash
# Check current security configuration
curl http://localhost:8000/security/status

# Test API2 - Unsigned JWT (alg:none)
curl -H "Authorization: Bearer eyJhbGciOiJub25lIiwidHlwIjoiSldUIn0.eyJzdWIiOiJlbXBfMDAyIiwibmFtZSI6IkJvYiJ9." \
  http://localhost:8000/api/orders

# Test API9 - Legacy endpoint (no auth)
curl http://localhost:8000/api/v1/orders

# Test API7 - SSRF target
curl http://localhost:8000/mock/internal/metadata

# Test API8 - Debug endpoint
curl http://localhost:8000/debug/logs

Promptfoo Configuration

The promptfooconfig.yaml is pre-configured with:

  • Plugin: owasp:api - Tests all OWASP API Security Top 10 vulnerabilities
  • Strategies: jailbreak:meta, crescendo, jailbreak:hydra

Expected Results

At SECURITY_*=1 (vulnerable), the red team should find:

  • BOLA attacks via prompt injection to access other users' data
  • SSRF via fetch tool to internal endpoints
  • Sensitive data exposure (salaries, SSNs, cost prices)
  • Legacy API access without authentication

At SECURITY_*=3 (secure), most attacks should be blocked.

Web UI

Visit http://localhost:8000 in your browser for the chat interface.

API Endpoints

Chat

  • POST /chat/ - Send message, get response with tool calls
  • GET /chat/sessions - List user's sessions

Auth

  • POST /auth/login - Get JWT token
  • GET /auth/demo-users - List available demo users

Mock Services

  • GET /mock/shipping/track/{tracking} - Track package
  • GET /mock/weather/{location} - Weather data
  • GET /mock/promotions/current - Current promos

Debug (vulnerable)

  • GET /debug/logs - Exposes JWT secret
  • GET /debug/config - Server configuration

Legacy v1 (vulnerable)

  • GET /api/v1/orders - All orders without auth
  • GET /api/v1/users - All users without auth

Troubleshooting

MCP Server Issues

bash
# Check Node.js for filesystem MCP
which npx

# Check uv for SQLite/Fetch MCP
which uvx

Database Issues

bash
# Re-seed the database
uv run python scripts/seed_database.py

API Key Issues

bash
# Verify API key is set
grep ANTHROPIC_API_KEY .env
