# Chrome on Mac: flaw lets a compromised renderer run code outside sandbox

Link for people: https://infrastack.ai/live/CVE-2026-126902 (this .md is for agents)

Google Chrome on macOS has an incorrect reference resolution flaw in its browser component. A remote attacker who has already compromised the renderer process can run arbitrary code outside the sandbox by serving a crafted HTML page.

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

## How to check

- Check the Chrome version on the Mac: open Chrome's About page or run `/Applications/Google Chrome.app/Contents/MacOS/Google Chrome --version`
- Compare the installed version against `157.0.8103.78`; anything older is in the affected range

## Fix

- Google Chrome on Mac: update to `157.0.8103.78` or later

## Timeline

- 2026-11-11T23:29:40+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-126902

## From the sources

Incorrect reference resolution in Browser in Google Chrome on on Mac prior to 157.0.8103.78 allowed a remote attacker who had compromised the renderer process to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High)
