CVE-2023-0704 is an insufficient policy enforcement vulnerability in the DevTools component of Google Chrome prior to version 110.0.5481.77. The flaw allows a remote attacker to bypass the same origin policy and proxy settings by enticing a user to visit a crafted HTML page. The vulnerability arises from inadequate enforcement of security policies within DevTools, potentially enabling cross-origin access or network policy circumvention.

This repository contains a single HTML file (exploit.html) with embedded JavaScript. The script demonstrates a browser-based proof-of-concept exploit that attempts to exfiltrate data from a cross-origin window. It opens a new window to a target web application (Rusty Notes at shellmates.club), waits for 5 seconds, and then tries to access the document body of the opened window. Due to browser same-origin policy, this access will typically fail unless a vulnerability or misconfiguration is present. Regardless of success or failure, the script exfiltrates either the content or the error message to an attacker-controlled webhook endpoint (webhook.site). The exploit is a POC and does not include a payload to bypass browser security, but demonstrates the intended attack flow. The repository is minimal, containing only the exploit file.
