Description

Improper Privilege Management in shelljs

Impact

Output from the synchronous version of shell.exec() may be visible to other users on the same system. You may be affected if you execute shell.exec() in multi-user Mac, Linux, or WSL environments, or if you execute shell.exec() as the root user.

Other shelljs functions (including the asynchronous version of shell.exec()) are not impacted.

Patches

Patched in shelljs 0.8.5

Workarounds

Recommended action is to upgrade to 0.8.5.
