Security Features

This application implements multiple layers of security:

Code Execution Security

  • Sandboxed Execution: All generated code runs in isolated environments
  • Resource Limits: CPU, memory, and timeout constraints prevent resource exhaustion
  • No eval(): Uses Function constructor with sanitized scope
  • CSP Enforcement: Content Security Policy in all execution contexts

Input Validation

  • All user inputs are sanitized before processing
  • API prompts are length-limited and validated
  • Package names are filtered against a blocklist
  • Path traversal attempts are detected and blocked

API Security

  • API keys should be stored securely (never in code)
  • Rate limiting on API calls
  • Automatic retry with exponential backoff

Reporting a Vulnerability

If you discover a security vulnerability, please follow these steps:

  1. DO NOT create a public GitHub issue
  2. Email security details to: [security@yourcompany.com]
  3. Include:
    • Description of the vulnerability
    • Steps to reproduce
    • Potential impact
    • Suggested fix (if any)

We will acknowledge receipt within 48 hours and provide updates every 72 hours.

Security Best Practices

For Users

  1. API Key Management

    • Never share your API key
    • Store API keys in secure files with restricted permissions
    • Rotate API keys regularly
    • Use environment variables for API keys in production
  2. Code Review

    • Always review generated code before execution
    • Be cautious with code that requests network access
    • Avoid executing code that accesses sensitive files
  3. Updates

    • Keep the application updated to the latest version
    • Run npm audit regularly to check for vulnerabilities
    • Update dependencies promptly

For Developers

  1. Secure Coding

    // NEVER do this
    eval(userInput);
    
    // Use this instead
    const func = new Function('sanitizedScope', code);
    func.call(null, limitedScope);
  2. Input Validation

    // Always validate IPC inputs
    ipcMain.handle('api-call', async (event, input) => {
        if (!validateInput(input)) {
            throw new Error('Invalid input');
        }
        // Process validated input
    });
  3. Sensitive Data

    • Never log sensitive information
    • Use electron's safeStorage for encryption
    • Clear sensitive data from memory after use

Security Checklist

Before deploying to production:

  • Enable renderer process sandbox
  • Implement API key encryption
  • Add rate limiting to all endpoints
  • Enable CSP headers
  • Remove all console.log statements with sensitive data
  • Run security audit: npm audit
  • Test with limited user permissions
  • Review all external package dependencies
  • Implement request signing for API calls
  • Add monitoring and alerting for security events

Known Security Considerations

  1. Electron Security

    • Renderer sandbox should be enabled in production
    • Context isolation must remain enabled
    • Node integration should stay disabled
  2. Code Generation

    • AI-generated code may contain vulnerabilities
    • Always validate and test generated code
    • Use the built-in security scanner before execution
  3. Network Security

    • API calls are made over HTTPS
    • No sensitive data in URL parameters
    • Request/response logging excludes sensitive fields

Security Headers

The application enforces these security headers:

Content-Security-Policy: default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline';
X-Content-Type-Options: nosniff
X-Frame-Options: DENY
X-XSS-Protection: 1; mode=block

Dependency Security

Regular dependency audits are performed:

# Check for vulnerabilities
npm audit

# Auto-fix when possible
npm audit fix

# Update dependencies
npm update
