There is a zero day vulnerability in Chrome that Google has issued a patch for. If you’re running Chrome, you must update as soon as possible. We’ve sent notifications to the managed and co-managed Macs we run.
To make sure you’re at the latest version, Chrome users can visit chrome://settings/help. If you need an update, it will let you know. Regardless, to be up to date, you need to be at version 100.0.4896.60 (at least).
This affects every Chrome-based browser (including Opera, Edge, Brave) and every operating system.
