We actively support the following versions with security updates:

We take security vulnerabilities seriously. If you discover a security vulnerability in the Devtools Performance Insights, please report it responsibly.

Please do NOT report security vulnerabilities through public GitHub issues.

Instead, please report security vulnerabilities to:

• Email: security@project.com
• Subject: "Security Vulnerability Report - Chrome Performance Analyzer"

Please include the following information in your report:

1. Description: A clear description of the vulnerability
2. Steps to Reproduce: Detailed steps to reproduce the issue
3. Impact: Potential impact and attack scenarios
4. Affected Versions: Which versions are affected
5. Proof of Concept: If applicable, include a PoC (responsibly)
6. Suggested Fix: If you have ideas for fixing the issue

Subject: Security Vulnerability Report - Chrome Performance Analyzer

Description:
The file upload functionality allows uploading files larger than the configured limit, potentially leading to DoS attacks.

Steps to Reproduce:
1. Navigate to the upload page
2. Attempt to upload a file larger than 50MB
3. The file is processed despite the limit

Impact:
- Server resource exhaustion
- Potential denial of service
- Memory consumption issues

Affected Versions:
- v1.0.0 to v1.2.3

Proof of Concept:
[Attach minimal PoC if applicable]

Suggested Fix:
Implement server-side file size validation before processing.

We aim to respond to security reports according to the following timeline:

• Initial Response: Within 24 hours
• Vulnerability Assessment: Within 72 hours
• Fix Development: Within 7 days (for critical issues)
• Security Release: Within 14 days
• Public Disclosure: 30 days after fix release

1. Input Validation

   • File type validation for uploads
   • File size limits
   • JSON schema validation for performance profiles

2. Content Security Policy (CSP)

   • Strict CSP headers
   • No inline scripts or styles
   • Restricted resource loading

3. Data Handling

   • Client-side processing only
   • No server-side data storage
   • Secure file handling

4. Dependencies

   • Regular dependency updates
   • Automated vulnerability scanning
   • Minimal dependency footprint

When contributing to this project, please follow these security guidelines:

// ✅ Good - Validate all inputs
function parsePerformanceProfile(file: File): PerformanceData {
  if (file.size > MAX_FILE_SIZE) {
    throw new Error('File too large')
  }
  
  if (!file.type.includes('json')) {
    throw new Error('Invalid file type')
  }
  
  // Additional validation...
}

// ❌ Bad - No validation
function parsePerformanceProfile(file: File): PerformanceData {
  return JSON.parse(await file.text())
}

// ✅ Good - Sanitize data
function displayMetricValue(value: unknown): string {
  if (typeof value !== 'number' || !isFinite(value)) {
    return 'Invalid'
  }
  return value.toFixed(2)
}

// ❌ Bad - Direct output
function displayMetricValue(value: unknown): string {
  return String(value)
}

// ✅ Good - Safe error handling
try {
  const data = parseProfile(file)
  return processData(data)
} catch (error) {
  console.error('Profile parsing failed')
  throw new Error('Invalid performance profile')
}

// ❌ Bad - Exposing internal details
try {
  const data = parseProfile(file)
  return processData(data)
} catch (error) {
  throw error // May expose sensitive information
