Attack-Flow Graph

Executive Summary

This vulnerability is an incorrect authorization issue in the Sandbox component of Google Chrome before version 152.0.7977.65. It allows a remote attacker who has already compromised the renderer process to potentially execute arbitrary code outside the sandbox by using a specially crafted HTML page.

Impact Analysis

If you use an affected version of Chrome, an attacker could exploit this flaw to run malicious code on your system even if they only compromised the browser's renderer process. This could lead to unauthorized access, data theft, or further compromise of your device.

Mitigation Strategies

Update Google Chrome to version 152.0.7977.65 or later to address the incorrect authorization issue in the Sandbox component.
