Address bar spoofing risk in ArcSearch on Android

ArcSearch for Android versions prior to 1.12.7 could display a different domain in the address bar than the content being shown, enabling address bar spoofing after user interaction via crafted web content.

Arc before 1.26.1 on Windows has a bypass issue in the site settings that allows websites (with previously granted permissions) to add new permissions when the user clicks anywhere on the website.
