A spoofing vulnerability manifests in Microsoft Xamarin.Forms due to the default settings on Android WebView version prior to 83.0.4103.106. This vulnerability could allow an attacker to execute arbitrary Javascript code on a target system.
For the attack to be successful, the targeted user would need to browse to a malicious website or a website serving the malicious code through Xamarin.Forms.
The security update addresses this vulnerability by preventing the malicious Javascript from running in the WebView.
