Include:
- Description of the vulnerability
- Steps to reproduce

- **Acknowledgment** within 48 hours
- **Initial assessment** within 7 days
- **Resolution timeline** based on severity
- **Credit** in release notes (if desired)

## Security Best Practices

When self-hosting SocialiseIT:

1. **Environment Variables** — Never commit `.env` files. Use `stack.env.example` as a template.
2. **Database** — Use strong passwords and restrict network access.
3. **OAuth Credentials** — Rotate secrets periodically and use restrictive scopes.
4. **Docker** — Keep images updated and run containers as non-root.
5. **Reverse Proxy** — Use HTTPS with a proper SSL certificate (Let's Encrypt).

## Authentication & Encryption

- Passwords are hashed with **bcrypt** (cost factor 12)
- OAuth tokens are encrypted at rest
- All API communication should be over HTTPS
- **Two-factor authentication (TOTP)** — optional per-user 2FA via authenticator apps

## Rate Limiting

- Registration endpoint: 10 requests/minute per IP
- API endpoints: configurable rate limits via middleware

## Webhook Verification

- **Meta** — HMAC-SHA256 signature verification with timing-safe comparison
- **Shopify** — HMAC-SHA256 signature verification
- **Stripe** — Webhook signature verification via Stripe SDK
