Details

Arbitrary Command Injection due to Improper Command Sanitization ### Summary 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. ### Impact Arbitrary Command Injection ### Details `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. ### Patches This issue has been patched in release `2.0.8` ### Acknowledgements This report was reported to us by @tyage (Ierae Security) through the [GitHub Bug Bounty Program](https://bounty.github.com).
