Sandbox escape via improper Views initialization

Published Sep 9, 2026 · Updated Sep 10, 2026

Improper initialization in Google Chrome Views before 153.0.8010.36 on Windows allows remote attackers to execute code outside the sandbox. Google has not disclosed which Views object is left uninitialized or how crafted HTML causes the invalid state to cross the sandbox boundary. Exploitation requires a compromised renderer process and social engineering that induces interaction with a crafted HTML page.
