Attack-Flow Graph

Executive Summary

This vulnerability involves insufficient validation of untrusted input in the WebView component of Google Chrome on Android. A remote attacker who has compromised the renderer process could exploit this to leak cross-origin data by using a specially crafted HTML page.

Detection Guidance

This vulnerability is specific to Google Chrome on Android versions prior to 151.0.7922.72. Detection requires checking the installed Chrome version on Android devices.
