Versions of tree-kill prior to 1.2.2 are vulnerable to Command Injection. The package fails to sanitize values passed to the kill function. If this value is user-controlled it may allow attackers to run arbitrary commands in the server. The issue only affects Windows systems.

Recommendation

Upgrade to version 1.2.2 or later.
