7.5 CVE-2025-37097

An adversary, through a previously installed malicious application, injects code into the context of a web page displayed by a WebView component. Through the injected code, an adversary is able to manipulate the DOM tree and cookies of the page, expose sensitive information, and can launch attacks against the web application from within the web page. [Determine target web application] An adversary first needs to determine what web application they wish to target. [Create malicious application] An adversary creates an application, often mobile, that incorporates a WebView component to display the targeted web application. This malicious application needs to downloaded by a user, so adversaries will make this application useful in some way. [Get the victim to download and run the application] An adversary needs to get the victim to willingly download and run the application. [Inject malicious code] Once the victim runs the malicious application and views the targeted web page in the WebView component, the malicious application will inject malicious JavaScript code into the web application. This is done by using WebView's loadURL() API, which can inject arbitrary JavaScript code into pages loaded by the WebView component with the same privileges. This is often done by adding a script tag to the document body with a src destination to a remote location that serves malicious JavaScript code.
