Detection Guidance

This vulnerability involves missing authorization in Google Chrome's DataTransfer component. Detection primarily requires checking the installed Chrome version. Run 'google-chrome --version' or check via 'chrome://settings/help' for updates. If the version is below 155.0.8059.39, the system is vulnerable.
