Executive Summary

This vulnerability allows a website to enter fullscreen mode after a user click without showing the usual fullscreen notification (toast). This lack of notification can mislead users about which site they are on, especially if a malicious site uses this to display a fake user interface, such as a fake address bar.

Impact Analysis

The vulnerability can impact users by enabling malicious sites to trick them into believing they are on a legitimate site through a fake fullscreen UI, potentially leading to phishing attacks or other forms of deception that compromise user trust and security.
