Overview

expressfs is a package that adds fs routes to your express app like writeFile, readFile, et cetera.

Affected versions of this package are vulnerable to Arbitrary Code Injection. The package does not validate user input on several API endpoints, allowing attackers to run arbitrary commands in the system. The affected endpoints are: expressfs.appendFile, expressfs.cp, expressfs.create and expressfs.rmdir.
