CVE-2022-0144 Open this link in a new tabHow to fix?
Upgrade shelljs
to version 0.8.5 or higher.
Overview
shelljs is a wrapper for the Unix shell commands for Node.js.
Affected versions of this package are vulnerable to Improper Privilege Management. When ShellJS
is used to create shell scripts which may be running as root
, users with low-level privileges on the system can leak sensitive information such as passwords (depending on implementation) from the standard output of the privileged process OR shutdown privileged ShellJS
processes via the exec
function when triggering EACCESS errors.
Note: Thi only impacts the synchronous version of shell.exec()
.
