CVE-2026-14428Network attack vector

Sandbox escape via improper Dawn input validation

Published Jul 1, 2026 · Updated Jul 1, 2026

Improper input validation in Dawn in Google Chrome on Android before 150.0.7871.46 allows remote attackers to escape the sandbox. Google has not disclosed the specific Dawn code locus or the untrusted input that it validates incorrectly. A crafted HTML page must first compromise the renderer process; the flaw then permits execution beyond that renderer sandbox, with confidentiality, integrity, and availability impact.
