How the Exploit Works

The vulnerability resides in the AJAX action and REST endpoint functions of the Royal Elementor Addons and Templates WordPress plugin. These functions do not properly enforce access control, allowing unauthenticated users to access sensitive content. An attacker can exploit this flaw by sending properly crafted AJAX requests to the vulnerable endpoints, thereby gaining access to draft, private, and password-protected posts/pages.

Conceptual Example Code

A potential exploitation of this vulnerability might look like the following HTTP request:

GET /wp-json/elementor/v2/posts/1234 HTTP/1.1
Host: vulnerable-website.com

In this example, the attacker sends a GET request to the REST endpoint of a post (with ID 1234), bypassing the access control and retrieving the content of that post.
