secure-file-upload

What problem does it solve?

This skill helps teams design and review secure file upload flows to prevent malware, data leakage, path traversal, and storage abuse.

Core Features & Use Cases

• Input validation and size checks at the server edge; MIME type and magic-byte verification; filename sanitization to prevent path traversal.
• Safe storage isolation and access-controlled delivery using private storage with signed URLs.
• Malware scanning integration (ClamAV, VirusTotal) and policy enforcement for uploads.
• Audit-ready reports and error handling for security incidents.

Quick Start

Review or design a secure file upload endpoint to apply validation, isolation, and malware scanning patterns.
