## Affected

- Netskope Netskope Client: fixed in 123.0; fixed in 117.1.11.2310; fixed in 120.1.10.2306

## Description

Netskope Client on Mac OS is impacted by a vulnerability in which the postinstall script does not properly validate the path of the file “nsinstallation”. A standard user could potentially create a symlink of the file “nsinstallation” to escalate the privileges of a different file on the system. This issue affects Netskope Client: before 123.0, before 117.1.11.2310, before 120.1.10.2306.

## What to do

- Check your stack: if you ship or depend on Netskope Netskope Client, upgrade to a fixed version (123.0, 117.1.11.2310, 120.1.10.2306) per the references below.
