🔒 Reporting Security Vulnerabilities

We take security seriously. If you discover a security vulnerability in SuperClaude Framework, please help us address it responsibly.

Responsible Disclosure

Please do NOT create public GitHub issues for security vulnerabilities.

Instead, email us directly at: anton.knoery@gmail.com (or create a private GitHub Security Advisory)

What to Include

When reporting a vulnerability, please provide:

• Description of the vulnerability and potential impact
• Steps to reproduce the issue with minimal examples
• Affected versions and components
• Suggested fixes if you have any ideas
• Your contact information for follow-up questions

Response Timeline

• Initial response: Within 48 hours of report
• Severity assessment: Within 1 week
• Fix timeline: Depends on severity (see below)
• Public disclosure: After fix is released and users have time to update

🚨 Severity Levels

Critical (Fix within 24-48 hours)

• Remote code execution vulnerabilities
• Privilege escalation that affects system security
• Data exfiltration or unauthorized access to sensitive information

High (Fix within 1 week)

• Local code execution through framework component manipulation
• Unauthorized file system access beyond intended scope
• Authentication bypass in MCP server communication

Medium (Fix within 1 month)

• Information disclosure of non-sensitive data
• Denial of service through resource exhaustion
• Input validation issues with limited impact

Low (Fix in next release)

• Minor information leaks
• Configuration issues with security implications
• Dependency vulnerabilities with low exploitability

🔐 Supported Versions

Version	Supported
4.0.0-beta.x	✅ Active Development
3.0.x	⚠️ Security fixes only
< 3.0	❌ End of life

🛡️ Security Features

Framework Component Security (V4 Enhanced)

• Timeout protection: All components have configurable timeouts (default 30s)
• Input validation: JSON schema validation for all component inputs
• Sandboxed execution: Components run with limited system permissions
• Error containment: Component failures don't affect framework stability
• Performance monitoring: Real-time component execution tracking
• Session lifecycle integration: Secure checkpoint and recovery

File System Protection

• Path validation: Prevents directory traversal attacks
• Permission checking: Validates file system permissions before operations
• Secure defaults: Conservative file access patterns
• Backup mechanisms: Safe fallback when operations fail

MCP Server Security (6 Servers in V4)

• Server validation: Verify MCP server authenticity and integrity
• Communication encryption: Secure channels for all MCP communication
• Timeout handling: Prevent resource exhaustion from unresponsive servers
• Fallback mechanisms: Graceful degradation when servers are compromised
• Serena MCP: Secure memory management with access controls
• Morphllm MCP: Validated file editing with permission checks

Configuration Security

• Input sanitization: All configuration inputs are validated and sanitized
• Secrets management: Secure handling of API keys and sensitive data
• Permission controls: Fine-grained access controls in settings.json
• Audit logging: Track security-relevant configuration changes

🔧 Security Best Practices

For Users

Installation Security

# Verify installation scripts before running
cat install.sh | less

# Use development mode for testing
./install.sh --dev

# Check file permissions after installation
ls -la ~/.claude/

Configuration Security

{
  "permissions": {
    "deny": [
      "Bash(rm:-rf /*)",
      "Bash(sudo:*)",
      "WebFetch(domain:localhost)"
    ]
  }
}

Regular Maintenance

• Update regularly: Keep SuperClaude and dependencies current
• Review logs: Check ~/.claude/ for suspicious activity
• Monitor permissions: Ensure components have minimal required permissions
• Validate configurations: Use provided schemas to validate settings

For Developers

Component Development

# Always validate inputs
def validate_input(data: Dict[str, Any]) -> bool:
    required_fields = ["tool", "data"]
    return all(field in data for field in required_fields)

# Handle errors gracefully
try:
    result = process_data(input_data)
except Exception as e:
    return {"status": "error", "message": "Processing failed"}

# Use timeouts for external calls
import signal
signal.alarm(10)  # 10-second timeout

Secure Coding Guidelines

• Input validation: Validate all external inputs
• Error handling: Never expose internal state in error messages
• Resource limits: Implement timeouts and resource limits
• Principle of least privilege: Request minimal required permissions

📋 Security Checklist

Before Release

• All dependencies updated to latest secure versions
• Static security analysis run (bandit, safety)
• Input validation tests pass
• Permission model reviewed
• Documentation updated with security considerations

Regular Maintenance

• Monthly dependency security updates
• Quarterly security review of codebase
• Annual third-party security assessment
• Continuous monitoring of security advisories

🤝 Security Community

Bug Bounty Program

Currently, we don't have a formal bug bounty program, but we recognize security researchers who help improve SuperClaude's security:

• Public acknowledgment in release notes and security advisories
• Early access to new features and versions
• Direct communication with the development team

Security Advisory Process

1. Internal assessment of reported vulnerability
2. Fix development with thorough testing
3. Coordinated disclosure with security researcher
4. Public advisory published after fix release
5. Post-mortem to prevent similar issues
