Overview

cookiecutter is a command-line utility that creates projects from cookiecutters.

Affected versions of this package are vulnerable to Command Injection via hg argument injection. When calling the cookiecutter function from Python code with the checkout parameter, it is passed to the hg checkout command in a way that additional flags can be set. The additional flags can be used to perform a command injection.

PoC 

from cookiecutter.main import cookiecutter

checkout = "--config=alias.checkout=!touch ./HELLO"
cookiecutter('some valid hg repository', checkout=checkout)
