CVE-2024-10858 is a DOM-based cross-site scripting vulnerability in the Jetpack WordPress plugin affecting 13.x versions prior to 14.1. The flaw is caused by improper validation of the origin of postMessage events, allowing the origin check to be bypassed. As a result, attacker-controlled data can be processed by client-side JavaScript in a way that leads to DOM-XSS. According to the provided content, the issue only affects websites hosted on WordPress.com.

This repository contains a single HTML file (index.html) that serves as a proof-of-concept (PoC) for a cross-site scripting (XSS) vulnerability targeting the Zerodha z-connect WordPress site. The exploit is implemented in JavaScript within the HTML file. When the user clicks the provided button, the script opens the target site (https://zerodha.com/z-connect/) in a new window and repeatedly sends a crafted postMessage payload. The payload is designed to exploit a potential vulnerability in the target site's handling of postMessage events, specifically by sending a message of type 'subscriptionModalShow' with a 'url' field containing a JavaScript URI that triggers an alert displaying the document domain. The exploit demonstrates the XSS vulnerability if the target site processes the message and executes the JavaScript. The repository is a simple, standalone PoC and does not use any exploit frameworks.
