Total: 0 Critical Issues, 8 Warnings, 50 Best Practices Implemented

1. Secrets Management ✅ EXCELLENT

Strengths

1.1 Vault-Managed Credentials with AppRole Authentication

✅ All core services use AppRole authentication (November 2025)

  • 7 services with AppRole: PostgreSQL, MySQL, MongoDB, Redis (3 nodes), RabbitMQ, Forgejo, Reference API
  • 9 services with root token: PGBouncer, additional reference apps, infrastructure services
  • No hardcoded passwords in any configuration files
  • Passwords loaded at runtime from Vault using service-specific credentials

AppRole Security Model:

# Each service authenticates with unique credentials
1. Container reads role-id and secret-id from mounted volume
2. Service logs into Vault: POST /v1/auth/approle/login
3. Receives short-lived service token (1h TTL, renewable)
4. Fetches credentials using service token
5. Token expires automatically after 1 hour

Implementation Example:

# docker-compose.yml (PostgreSQL with AppRole)
entrypoint: ["/init/init-approle.sh"]
environment:
  VAULT_ADDR: http://vault:8200
  VAULT_APPROLE_DIR: /vault-approles/postgres
volumes:
  - ${HOME}/.config/vault/approles/postgres:/vault-approles/postgres:ro

Security Benefits:

  • ✅ Zero root token usage in core service containers
  • ✅ Least-privilege access (each service sees only its own secrets)
  • ✅ Token expiration (1h TTL reduces attack window)
  • ✅ Audit trail (all AppRole logins logged by Vault)
  • ✅ Policy enforcement (cross-service access prevented)

1.2 Environment File Security

✅ Proper .env handling

# .env.example shows EMPTY passwords
POSTGRES_PASSWORD=  # Loaded from Vault at runtime

✅ Gitignore configured correctly

.env
*.env.local
**/keys.json
**/root-token

1.3 Secret Detection in CI/CD

✅ Multiple secret scanning tools

  • TruffleHog (verified secrets only)
  • Gitleaks
  • Custom regex patterns
  • detect-secrets baseline file (.secrets.baseline)

✅ Pre-commit hook for detect-secrets

# .pre-commit-config.yaml
- repo: https://github.com/Yelp/detect-secrets
  rev: v1.4.0
  hooks:
    - id: detect-secrets
      args: ['--baseline', '.secrets.baseline']

1.4 Password Masking in API Responses

✅ Vault router masks passwords

# app/routers/vault_demo.py
if "password" in result:
    result["password"] = "******"  # Mask passwords

Warnings

⚠️ ROOT_TOKEN_WARNING - Some services still use Vault root token

  • Core services (7): ✅ Migrated to AppRole (November 2025)
  • Infrastructure (9): ⚠️ Still use root token (migration planned for Phase 4+)
  • Risk: Root token has unlimited privileges
  • Mitigation: Root token only used for non-core services and management
  • Status: 43.75% AppRole adoption (7/16 Vault-integrated services)

Services Using Root Token:

  • PGBouncer (connection pooler)
  • Additional reference apps (api-first, golang, nodejs, rust)
  • Infrastructure (redis-exporters x3, vector)

AppRole Migration Roadmap:

  • ✅ Phase 1 (Nov 2025): Core data tier - COMPLETED
  • 📋 Phase 4.1 (Planned): Reference applications
  • 📋 Phase 4.2 (Planned): Infrastructure services
  • 🎯 Target: 95%+ AppRole adoption (15/16 services)

Documentation: See docs/VAULT_SECURITY.md for AppRole implementation details

2. Authentication & Authorization ⚠️ BY DESIGN

Strengths

2.1 Rate Limiting

✅ slowapi rate limiting implemented

# app/main.py
limiter = Limiter(key_func=get_remote_address)

@app.get("/")
@limiter.limit("100/minute")  # Per-IP rate limiting

Rate limits configured:

  • General endpoints: 100/minute
  • Metrics endpoint: 1000/minute
  • Health checks: 200/minute

2.2 Circuit Breaker Pattern

✅ pybreaker prevents cascading failures

# Configured for all external services
- Vault, PostgreSQL, MySQL, MongoDB, Redis, RabbitMQ
- failure_threshold: 5
- reset_timeout: 60s

Warnings (By Design for Development)

⚠️ NO_AUTH_WARNING - No authentication on API endpoints

  • Location: FastAPI reference application
  • Risk: Anyone can access all endpoints
  • Status: Intentional for development/testing
  • Documentation: Clearly stated in README

⚠️ DEBUG_MODE_WARNING - Debug mode enables CORS wildcard

# app/main.py (line 107-108)
if settings.DEBUG:
    CORS_ORIGINS = ["*"]  # Allow all origins in debug
  • Risk: CORS wildcard with credentials=True would be dangerous
  • Mitigation: allow_credentials=not settings.DEBUG prevents this

⚠️ NO_API_KEYS - No API key validation

  • Status: Reference implementation for learning
  • Recommendation: Implement OAuth2/JWT for production

Production Recommendations

For production deployment, implement:

  1. OAuth2 with JWT tokens - User authentication
  2. API key validation - Service-to-service auth
  3. AppRole authentication - Vault access
  4. Request signing - Prevent replay attacks
  5. Disable DEBUG mode - Restrict CORS origins

3. Container Security ✅ GOOD

Strengths

3.1 Pinned Image Versions

✅ All container images use specific versions

postgres: postgres:18
mysql: mysql:8.0.40
redis: redis:7.4-alpine3.21
vault: hashicorp/vault:1.18

3.2 Read-Only Volume Mounts

✅ Configuration files mounted read-only

volumes:
  - ./configs/postgres:/docker-entrypoint-initdb.d:ro
  - ./configs/postgres/scripts/init.sh:/init/init.sh:ro
  - ${HOME}/.config/vault/certs/postgres:/var/lib/postgresql/certs:ro

3.3 Non-Root Users

✅ Services run as non-root where possible

# Forgejo runs as UID 1000
environment:
  USER_UID: 1000
  USER_GID: 1000

3.4 Resource Limits Configured

✅ Memory and connection limits set

environment:
  POSTGRES_MAX_CONNECTIONS: 100
  REDIS_MAXMEMORY: 256mb
  MYSQL_MAX_CONNECTIONS: 100

3.5 Health Checks Implemented

✅ All services have health checks

healthcheck:
  test: ["CMD-SHELL", "pg_isready -U dev_admin"]
  interval: 60s
  timeout: 5s
  retries: 5
  start_period: 30s

3.6 Network Isolation

✅ Custom bridge network with static IPs

networks:
  dev-services:
    driver: bridge
    ipam:
      config:
        - subnet: 172.20.0.0/16

Warnings

⚠️ PRIVILEGED_CONTAINER - cAdvisor runs privileged

  • Location: docker-compose.yml:976
  • Service: cAdvisor (container monitoring)
  • Justification: Requires access to host Docker socket
  • Risk: Limited to monitoring service only
cadvisor:
  privileged: true  # Required for container metrics

⚠️ CAP_ADD - Vault uses IPC_LOCK capability

  • Location: docker-compose.yml:615
  • Service: Vault
  • Justification: Prevents memory swapping (security best practice for secrets)
  • Risk: Minimal - standard Vault requirement
vault:
  cap_add:
    - IPC_LOCK  # Prevent memory from being swapped to disk

Recommendations

  1. Add resource limits - CPU and memory limits for all services
  2. Consider read-only root filesystem - Where applicable
  3. Review cAdvisor alternatives - If concerned about privileged mode

4. Injection Vulnerabilities ✅ EXCELLENT

Strengths

4.1 SQL Injection Protection

✅ Parameterized queries only - NO string concatenation

PostgreSQL (asyncpg):

# SAFE: No user input in queries
result = await conn.fetchval("SELECT current_timestamp")
# All queries use static SQL strings

MySQL (aiomysql):

# SAFE: No user input in queries
await cursor.execute("SELECT NOW()")

MongoDB (motor):

# SAFE: No raw queries, uses Python objects
collections = await db.list_collection_names()

✅ No dynamic SQL construction found

  • Searched all database routers
  • All queries are static
  • No f-strings or string concatenation with user input

4.2 Command Injection Protection

✅ No shell command execution with user input

Searched for:

  • subprocess, os.system, os.popen, eval, exec
  • Result: No dangerous functions found in Python code

✅ Shell scripts use safe patterns

# vault-bootstrap.sh uses proper quoting
curl -s -X POST "${VAULT_ADDR}/v1/sys/mounts/pki" \
  -H "X-Vault-Token: ${VAULT_TOKEN}"

4.3 NoSQL Injection Protection

✅ MongoDB queries use driver objects

# SAFE: No raw query strings
client = motor.motor_asyncio.AsyncIOMotorClient(uri)
collections = await db.list_collection_names()

4.4 Redis Command Injection Protection

✅ Redis commands use driver methods

# SAFE: Using execute_command with static strings
cluster_nodes_raw = await client.execute_command("CLUSTER", "NODES")

4.5 Input Validation

✅ Pydantic v2 data models validate all input

# app/models/responses.py
class StandardResponse(BaseModel):
    status: str
    message: Optional[str] = None
    data: Optional[Dict[str, Any]] = None

Findings

0 SQL injection vulnerabilities found 0 Command injection vulnerabilities found 0 NoSQL injection vulnerabilities found 0 Unsafe string concatenation patterns found

5. Network Security ✅ GOOD

5.3 HTTPS Support for Reference API

✅ Dual HTTP/HTTPS mode

reference-api:
  ports:
    - "8000:8000"   # HTTP
    - "8443:8443"   # HTTPS
  environment:
    REFERENCE_API_ENABLE_TLS: true

5.4 Service Dependencies

✅ Proper startup ordering

depends_on:
  vault:
    condition: service_healthy

Warnings

⚠️ HTTP_DEFAULT - HTTP is default for development

  • Risk: Unencrypted traffic in development
  • Mitigation: TLS can be enabled via environment variables
  • Status: Appropriate for local development

Recommendations

  1. Enable TLS by default - Set *_ENABLE_TLS=true in .env.example
  2. Document TLS setup - Make it easier for users to enable encryption
  3. Add TLS validation - Test certificate validation in client connections
