Attack-Flow Graph

Executive Summary

This vulnerability is due to an inappropriate implementation in the DataTransfer component of Google Chrome on Mac systems prior to version 150.0.7871.47. It allows a remote attacker to leak cross-origin data by convincing a user to perform specific user interface gestures on a crafted HTML page.

Impact Analysis

The vulnerability can lead to unauthorized leakage of data from different origins, potentially exposing sensitive information to attackers. This occurs when a user is tricked into performing certain UI gestures, which then allows the attacker to access data that should be isolated by the browser's same-origin policy.
