Summary
degit has a Command Injection issue
Details

Versions of the package degit before 2.8.6, from 3.0.0 and before 3.3.1 are vulnerable to Command Injection due to improper sanitisation of user input for git shell commands directly invoked with exec() method by _cloneWithGit() and fetchRefs() functions. An attacker can execute arbitrary operating system commands as the process user by supplying a specially crafted git repository name.
