CVE-2021-21224
HIGH ⌖ ON CISA KEV · EXPLOITEDA type confusion vulnerability in Google Chromium V8 allowed remote code execution inside a browser sandbox via a crafted HTML page.
The vulnerability in the Chromium V8 engine enabled attackers to execute arbitrary code within the browser's sandbox, posing a significant risk to any organization relying on Chromium-based browsers like Chrome or Edge. For DIB organizations, this highlights the critical need for timely patching of widely used components and the inherent risks of relying on open-source engines that may be exploited in the wild before patches are applied. Organizations should enforce strict update policies and consider alternative browsers if patching cannot be guaranteed.
Shame score — A type confusion vulnerability in a foundational browser engine was actively exploited in the wild (KEV), demonstrating that even major vendors can ship with exploitable flaws that compromise user systems before patches are widely deployed.
▸ RECOMMENDED ACTION Actively exploited (CISA KEV) — remediate now, ahead of your normal patch cycle.
