Description · from the CVE record

git-diff before 2.0.7 contains an OS command injection vulnerability that allows attackers to execute shell commands by supplying crafted strings to the gitDiff API. Attackers who control a diffed document string can embed $(cmd) or backtick substitutions that shelljs.exec evaluates, running commands with Node.js process privileges.
