WebView Security: A Browser With Your App's Identity

A WebView is a browser engine inside an app, with no address bar and whatever powers the app adds. Most WebView bugs come from three choices: a JavaScript bridge exposed to every frame, file and content access that let a page read local data, and loading content the app does not control, such as deep-link URLs and model-generated HTML. The defences: separate trusted and untrusted content, give local files a real origin, use origin-restricted message channels, and send external links and login to the system browser.
