CVE-2026-87500 is a high-severity improper array-index validation vulnerability in ANGLE, the graphics translation layer used by Chromium-based browsers. Google Chrome versions prior to 153.0.8010.36 inadequately validate an array index while processing attacker-controlled web content. A remote attacker can use a crafted HTML page to trigger the flaw and potentially execute arbitrary code outside the browser sandbox.
