# Google Chrome on Mac: Chromoting flaw lets a local program read sensitive data

Chrome's Chromoting remote-desktop component on Mac lacks an authorization check before versions prior to 157.0.8103.38. A local program on the same machine can obtain sensitive information.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Chrome version in Chrome's About page or with `google-chrome --version` on Linux; Mac users check Chrome > About Google Chrome.
- Confirm whether Chrome Remote Desktop (Chromoting) is installed or used on the Mac: unknown if the sources say more.

## Fix

- Google Chrome on Mac: move to `157.0.8103.38` or later.

## Timeline

## From the sources

Missing authorization in Chromoting in Google Chrome on on Mac prior to 157.0.8103.38 allowed a local attacker to obtain sensitive information via a local program. (Chromium security severity: Medium)
