filebouncer
npm package for detecting suspicious uploads.
If you're building a Node.js upload endpoint, you shouldn't have to implement every file-security check yourself. A `.jpg` can also be a ZIP file. You can create a polyglot file by combining a valid JPEG and ZIP: cat photo.jpg secret.zip > polyglot.jpg Most applications will detect `image/jpeg`, while the same file also contains a ZIP archive. That's why I built filebouncer, a node file security library that detects MIME mismatches, polyglot files, unsafe archive paths, archive size issues.
