  1. Check whether you run it. Look for Chromium WebRTC in your asset inventory, including appliances and cloud images. Stack check lists every exploited Google CVE at once.
  2. Apply the fix. Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
  3. If you can't patch today, take the affected service off the internet or restrict who can reach it, and check its logs for signs of compromise since 21 Dec 2023.
  4. Get told next time. Email alerts when CISA adds a CVE for Google.
