Senserva AI Opinion for CVE-2020-16013

Another exploited Chromium V8 flaw, this inappropriate implementation bug lets a crafted HTML page corrupt the heap and execute code in the renderer. It affects the whole Chromium family, so Edge and other derivative browsers were exposed alongside Chrome. Exploitation in the wild was confirmed even though the EPSS score sits at just 3 percent.

Do this: Verify browser auto-update is enforced by policy on all endpoints rather than left to user discretion.
