Smart Lock Manager takes security seriously. As a component that manages physical lock access codes, we implement comprehensive security measures to protect your smart home and sensitive data.

Security updates are provided for the following versions:

⚠️ IMPORTANT: Do NOT report security vulnerabilities in public issues.

If you discover a security vulnerability, please report it responsibly:

1. Email: Send details to [email protected]
2. GitHub Security Advisory: Use GitHub's private vulnerability reporting

Please include the following information in your report:

• Component affected: Which part of Smart Lock Manager
• Vulnerability type: Classification (injection, authentication, etc.)
• Impact assessment: Potential consequences
• Reproduction steps: How to reproduce the issue
• Proof of concept: Example code or demonstration (if safe to share)
• Suggested fix: If you have ideas for resolution
• Disclosure timeline: Your preferred timeline for public disclosure

We prioritize vulnerabilities in these areas:

• High Priority:

  • PIN code exposure or logging
  • Authentication bypass
  • Code injection attacks
  • Unauthorized lock control
  • Data exposure in logs or storage

• Medium Priority:

  • Service validation bypass
  • Frontend security issues
  • API authentication weaknesses
  • Information disclosure

• Lower Priority:

  • UI-only vulnerabilities
  • Documentation issues
  • Non-security functionality bugs

• PIN Code Validation: Strict numeric validation (4-8 digits)
• SQL Injection Prevention: Parameterized queries and ORM usage
• XSS Protection: Input sanitization in frontend components
• Command Injection Prevention: No shell command execution with user input

• PIN Code Masking: PIN codes never appear in logs as plaintext
• Secure Storage: Encrypted storage using Home Assistant's secure storage API
• Memory Protection: Sensitive data cleared from memory when not needed
• Debug Mode Safety: Debug logging excludes sensitive information

• Home Assistant Authentication: Leverages HA's built-in authentication
• Service Validation: All service calls validated for proper entity access
• Z-Wave Security: Respects Z-Wave JS security protocols
• API Endpoint Protection: Custom panel routes require authentication

• Security Event Logging: Logs security-relevant events
• Failed Attempt Tracking: Monitors and logs failed operations
• Audit Trail: Comprehensive logging of all lock operations
• Error Handling: Secure error messages that don't expose internals

We use multiple security tools in our CI/CD pipeline:

• Bandit: Python security vulnerability scanner
• Safety: Dependency vulnerability monitoring
• Vulture: Dead code detection (security hygiene)
• Pre-commit Hooks: Automated security checks on every commit

As of v2025.1.0:

• Security Scan Status: ✅ Passing (1 low-severity finding)
• Vulnerability Count: 0 known vulnerabilities
• Dependencies: All dependencies scanned and secure
• Test Coverage: Comprehensive security test suite

Our test suite includes:

• Input Validation Tests: PIN codes, slot numbers, date formats
• Injection Attack Tests: SQL, XSS, command injection attempts
• Authentication Tests: Service call authorization
• Data Exposure Tests: Log content verification
• Error Handling Tests: Secure error message validation

1. PIN Code Management:

   • Use unique, non-sequential PIN codes
   • Regularly rotate temporary codes
   • Set expiration dates for all codes
   • Monitor usage statistics for anomalies

2. System Security:

   • Keep Home Assistant updated
   • Use strong authentication for Home Assistant
   • Enable 2FA where possible
   • Regularly review access logs

3. Network Security:

   • Use encrypted Z-Wave communication
   • Secure your Home Assistant network
   • Monitor for unusual Z-Wave activity
   • Keep Z-Wave JS updated

• Critical Security Updates: Released immediately
• Important Security Updates: Released within 48 hours
• Security Enhancements: Included in regular releases

We will notify users of security updates through:

• GitHub Security Advisories: For critical vulnerabilities
• Release Notes: For all security-related changes
• HACS Updates: Automatic notification in Home Assistant
• Documentation Updates: Updated security guidance

For critical security issues:

1. Immediate Assessment: Within 2 hours of report
