User-assisted sandbox escape

Published Jul 16, 2024 · Updated Aug 2, 2024

Insufficient data validation in Google Chrome before 117.0.5938.62 allows attackers to escape the sandbox via a malicious file. The flaw resides in Permission Prompts, but Google has not published which file field is accepted incorrectly or how that value crosses the sandbox boundary. Exploitation requires convincing a user to install a malicious app and process its malicious file; the documented consequence is escape from Chrome's sandbox.
