Race Condition in Google Chrome Workers

Executive Summary

This is a race condition vulnerability in Google Chrome's Workers feature. A race condition occurs when the system's behavior depends on the timing of events, which can lead to unexpected outcomes. In this case, the vulnerability allows an attacker who has already compromised the renderer process to bypass the web origin policy. The web origin policy is a security feature that prevents scripts from one website from accessing data from another website. By bypassing this policy, the attacker could potentially access sensitive data from different origins.
