We take security seriously. If you discover a security vulnerability, please report it responsibly:

• Email: Create an issue on GitHub with the label "security"
• Response Time: We aim to respond within 48 hours
• Disclosure: Please allow us time to fix vulnerabilities before public disclosure

CRITICAL: Always use a secure, randomly generated authentication token:

# Generate a secure token (32 bytes = 256 bits)
openssl rand -hex 32
# Alternative method using Node.js
node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"

Never use:

• Default or example tokens
• Predictable patterns
• Short tokens (< 16 characters)
• Personal information in tokens

• Never commit .env files to version control
• Use .env.example as a template only
• Set NODE_ENV=production in production
• Regularly rotate authentication tokens

• Use HTTPS in production (see DOMAIN_SETUP.md)
• Consider IP whitelisting for API access
• Use a reverse proxy (nginx/Apache) for production
• Enable rate limiting and DDoS protection

• Don't run containers as root user
• Limit container resources (memory, CPU)
• Use specific image tags, not latest
• Regularly update base images

• Always validate the token parameter
• Use HTTPS for all API communications
• Monitor for unusual access patterns
• Log authentication failures

HeadlessX includes several security features:

1. Token-based Authentication: All API endpoints require authentication
2. Input Validation: URLs and parameters are validated
3. Resource Limits: Browser instances have timeout controls
4. Error Handling: Sensitive information is not exposed in error messages
5. CORS Protection: Cross-origin requests are controlled

• Generated a secure random token
• Set AUTH_TOKEN environment variable
• Removed all default/example tokens
• Configured HTTPS (for production)
• Set up proper firewall rules
• Enabled logging and monitoring
• Tested authentication
• Updated all dependencies

We recommend regularly updating dependencies:

# Check for vulnerabilities
npm audit
# Fix automatically fixable issues
npm audit fix
# Update all dependencies
npm update

For security concerns, please create a GitHub issue with the "security" label.
