Description
Arc Search for Android before version 1.12.10 does not display a fullscreen notification when a page enters fullscreen mode while the app is running in the background. A remote attacker can exploit this via a specially crafted website to render fake UI elements, such as a spoofed address bar, misleading the user about the origin of displayed content and increasing the risk of phishing.
