Affected versions of this package are vulnerable to Command Injection such that the package-exported method gitCommitInfo () fails to sanitize its parameter commit, which later flows into a sensitive command execution API. As a result, attackers may inject malicious commands once they control the hash content.

// information of the latest commit in ./my_repo
gitCommitInfo({
cwd: './my_repo',
commit: '82442c2405804d7aa44e7bedbc0b93bb17707626' + " || touch ci ||", // a malicious file named ci will be crated
});
