In an official blog post, Google revealed that a new ‘zero-day’ exploit (CVE-2021-30563) has been discovered in Chrome and — like the previous attack — it follows an anonymous tip-off. Unlike the majority of security flaws, a zero-day classification means the exploit has been made public before the company could patch it. Writing on its blog, Google confirmed it “is aware of reports that an exploit for CVE-2021-30563 exists in the wild.”
To combat this new threat, all Chrome users should navigate to Settings > Help > About Google Chrome. If your browser version on Linux, macOS and Windows is listed as 91.0.4472.164 or above you are already safe. If not, manually check for updates then restart the browser once the update is ready. Google has also confirmed that six other ‘High’ level threats are patched in this version of Chrome as well as a single ‘Medium’ level vulnerability.
