Executive Summary

This vulnerability in Whale browser versions before 4.33.325.17 allows an attacker to bypass the Same-Origin Policy when using a dual-tab environment. The Same-Origin Policy is a security measure that restricts how documents or scripts loaded from one origin can interact with resources from another origin. Bypassing this policy can enable unauthorized access between tabs.

Impact Analysis

By bypassing the Same-Origin Policy, an attacker could potentially access or manipulate data from another tab that should be isolated, leading to unauthorized data exposure or actions within the browser environment.
