CVE-2026-9969Network attack vector

Code execution via invalid ANGLE input

Published May 28, 2026 · Updated May 28, 2026

Insufficient input validation in ANGLE in Google Chrome before 148.0.7778.216 allows remote attackers to execute code via crafted HTML. Google identifies ANGLE as the affected component but has not disclosed which input path accepts invalid data or what validation is missing. A user must open the attacker-controlled page; successful exploitation runs code in Chrome's security context, and no sandbox escape is reported.
