There exists a command injection vulnerability in npmcli/git versions <2.0.8 which may result in arbitrary shell command execution due to improper argument sanitization when npmcli/git is used to execute Git commands based on user controlled input.
The impact of this issue is possible Arbitrary Command Injection when npmcli/git is run with untrusted (user controlled) Git command arguments.
Arbitrary Command Injection
npmcli/git prior to release 2.0.8 passed user controlled input as arguments to a shell command without properly sanitizing this input. Passing unsanitized input to a shell can lead to arbitrary command injection. For example passing git+https://github.com/npm/git; echo hello world would trigger the shell execution of echo hello world.
This issue was remediated by no longer running npmcli/git git commands through an intermediate shell.
This issue has been patched in release 2.0.8
