Attack-Flow Graph

Executive Summary

This vulnerability involves incorrect authorization in Google Chrome's FileSystem component. A remote attacker could exploit it through social engineering to potentially execute arbitrary code outside the sandbox by tricking a user into visiting a specially crafted HTML page.

Detection Guidance

This vulnerability cannot be directly detected with commands as it requires analyzing the specific version of Google Chrome installed. Check if your Chrome version is prior to 155.0.8059.39 using chrome://settings/help or system package managers.
