We actively support and provide security updates for the following versions:

This project implements several security measures:

• Archive Extraction: Uses safe extraction utilities to prevent directory traversal attacks
• Path Validation: All file paths are validated before processing
• Temporary Files: Secure temporary file creation and cleanup

• HTTPS Only: All downloads use HTTPS with certificate verification
• No Credentials: Application doesn't store or transmit user credentials
• Safe Downloads: FFmpeg binaries are downloaded from official sources only

• Command Injection Prevention: All user inputs are properly escaped and validated
• File Type Validation: Only supported video file types are processed
• Parameter Sanitization: FFmpeg parameters are sanitized before execution

• Isolated Execution: External processes run with minimal privileges
• Resource Limits: Conversion processes have reasonable resource constraints
• Clean Shutdown: Proper cleanup of processes and temporary files

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

1. DO NOT create a public GitHub issue for security vulnerabilities
2. Email the maintainers privately at: [[email protected]] (replace with actual email)
3. Include the following information:
   • Description of the vulnerability
   • Steps to reproduce
   • Potential impact assessment
   • Suggested fix (if you have one)

• Acknowledgment: We will acknowledge receipt within 24-48 hours
• Initial Assessment: We will provide an initial assessment within 7 days
• Fix Development: We aim to develop fixes within 30 days for critical issues
• Public Disclosure: We will coordinate public disclosure after a fix is available

Critical (CVSS 9.0-10.0)

• Remote code execution
• Arbitrary file access outside intended directories
• Privilege escalation

High (CVSS 7.0-8.9)

• Local file inclusion/disclosure
• Command injection with limited scope
• Authentication bypass

Medium (CVSS 4.0-6.9)

• Information disclosure
• Denial of service
• Cross-site scripting (if web interface added)

Low (CVSS 0.1-3.9)

• Minor information leakage
• Non-exploitable crashes
• Configuration issues

• Always download from official sources
• Verify checksums when available
• Use virtual environments for Python dependencies
• Keep FFmpeg updated to latest stable version

• Don't process untrusted video files from unknown sources
• Review FFmpeg commands before execution
• Keep output directories within user-accessible areas
• Regularly update the application and dependencies

• Run with standard user privileges (not root/administrator)
• Use updated operating systems with current security patches
• Enable firewall protection
• Scan downloaded files with antivirus software

• We regularly update dependencies to address security vulnerabilities
• Use pip-audit or similar tools to check for known vulnerabilities:

  pip install pip-audit
  pip-audit

• The application helps users download official FFmpeg binaries
• Users should verify FFmpeg signatures when possible
• We don't modify or redistribute FFmpeg binaries

• Updated safe extraction utilities
• Hardened HTTPS downloads with certificate verification
• Updated input validation and sanitization

• Added safe ZIP/TAR extraction utilities
• Implemented secure temporary file handling
• Added file size limits to prevent resource exhaustion

• Initial security implementation
• Basic input validation
• Safe external process execution
