to version 1.3.0 or higher.
@knutkirkhorn/free-space is a package that gets the amount of free space for a drive.
Affected versions of this package are vulnerable to Arbitrary Command Execution due to the lack of sanitization of the input parameter of the library's exported anonymous function. The exported function, when given a parameter checks what platform the code is being run on and sends that parameter to a function call in either lib/unix.js or lib/windows/js. The vulnerability exists in lib/unix.js which directly uses the user-input parameter: disk in the template string that ultimately gets executed.
