AI-analyzed exploit summary This repository contains a functional Python script that exploits an authentication bypass vulnerability in the MStore API WordPress plugin (versions <= 3.9.2). The exploit fetches user IDs via the REST API and crafts a request to the vulnerable endpoint to bypass authentication and log in as any user.

Description

The MStore API plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 3.9.2. This is due to insufficient verification on the user being supplied during the add listing REST API request through the plugin. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the user id.
