Security Considerations

File Access

• The tool only reads the file you specify
• No directory traversal or unauthorized file access
• Files are not modified or deleted
• File path validation prevents malicious inputs

Network Security

• Only communicates with https://litterbox.catbox.moe (HTTPS encrypted)
• Uses system curl command for secure file transmission
• No other external services are contacted
• No authentication tokens or API keys required
• Secure TLS connection for file transmission

Data Privacy

⚠️ Important: Files are uploaded to a public file sharing service:

• URLs are publicly accessible by anyone who has the link
• Files automatically expire after 72 hours
• No authentication or access control
• Do not upload sensitive, confidential, or private files
• User is responsible for file content and compliance

Dependencies

The tool uses:

• Native Node.js modules: child_process, fs, path, util
• System curl: Pre-installed on most systems, widely trusted and security-audited
• No external npm packages required

Limitations

• Maximum file size: 1GB (litterbox.catbox.moe service limit)
• File expiry: Files are automatically deleted after 72 hours
• Upload timeout: 60 seconds
• Single file: One file per command (no batch uploads)
• No retry logic: Failed uploads must be manually retried
• Public URLs: All uploaded files are publicly accessible
• Requires curl: System must have curl installed
