Executive Summary

This vulnerability is due to insufficient data validation in the DevTools component of Google Chrome versions prior to 150.0.7871.47. It allows a remote attacker to trick a user into performing specific user interface gestures, which then enables the attacker to leak cross-origin data through a specially crafted HTML page.

Impact Analysis

The impact of this vulnerability is that an attacker could potentially access data from other origins (websites) that should normally be isolated, by convincing the user to perform certain UI actions. This could lead to unauthorized disclosure of sensitive information across different websites.
