Navigate your browser to: chrome://settings/help
The most recent version as of 2021-07-16 is 91.0.4472.164
How do I mitigate this threat?
If you’re running an older version, then Chrome should update itself automatically on next launch. The About page can be used to manually update and this requires a relaunch of the browser.
