If you discover a security vulnerability, please email security@example.com or create a private security advisory on GitHub.

Please do not create public issues for security vulnerabilities.

Never commit sensitive credentials to the repository:

• ❌ .env files with real credentials
• ❌ API keys, passwords, tokens in code
• ❌ Database credentials in scripts

Always use:

• ✅ .env.example files as templates
• ✅ Environment variables for secrets
• ✅ .gitignore for sensitive files

The following files should never be committed:

.env
.env.worker
*.key
*.pem
credentials.json
secrets.yaml

Copy example files and configure with your own credentials:

# Copy configuration templates
cp .env.example .env
cp .env.worker.example .env.worker

# Edit with your credentials
nano .env
nano .env.worker

• Use strong passwords for database users
• Limit database user permissions to necessary operations
• Use environment variables for database credentials
• Never hardcode credentials in scripts

• Store API keys in .env files
• Never commit API keys to version control
• Rotate API keys regularly
• Use rate limiting for all endpoints

1. Never use default credentials

   • Change all default passwords
   • Generate strong, unique passwords
   • Use password managers

2. Environment separation

   • Use different credentials for dev/staging/production
   • Never use production credentials locally
   • Keep production secrets in secure vaults

3. Access control

   • Limit who has access to production credentials
   • Use SSH keys, not passwords
   • Enable 2FA for all accounts

4. Monitoring

   • Monitor for unauthorized access attempts
   • Set up alerts for suspicious activity
   • Regularly review access logs

The system implements circuit breaker patterns to prevent cascading failures:

• OpenAI API calls
• Database operations
• RSS feed fetching

Monitor circuit breaker status at: /api/v1/health/circuit-breakers

• Automatic retry with exponential backoff
• Error classification and targeted recovery
• Rate limiting to prevent abuse

• Kubernetes-ready liveness/readiness probes
• Database connectivity monitoring
• Service health tracking

• Critical Fix: Removed hardcoded database credentials from repository
• Moved .env.worker to .gitignore
• Created .env.worker.example template
• Removed hardcoded password from scripts/update_all_docs.sh

• Implemented Circuit Breaker pattern for fault tolerance
• Added comprehensive error recovery mechanisms
• Enhanced monitoring endpoints

• All sensitive data must be encrypted at rest
• API communications should use HTTPS in production
• Follow OWASP security guidelines
• Regular security audits recommended
