Original description

The Essential Addons for Elementor – Popular Elementor Templates & Widgets plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 6.8.7 via the `page_id` parameter of the `register_user()` function. The vulnerability exists because the handler's post status deny-list rejects `future`, `draft`, and `pending` but admits `inherit` — the status carried by every WordPress revision — allowing an attacker to substitute a revision ID for a live page ID, while a flawed "last saved by administrator" check reads `post_author` on revisions (which reflects the editing administrator) rather than the `_edit_last` meta that is never copied to revisions, and the nonce gate is rendered ineffective because any unauthenticated visitor can freely obtain a valid nonce via the `wp_ajax_nopriv_eael_get_token` endpoint. This makes it possible for unauthenticated attackers to register an account with a role as high as Editor — gaining capabilities including `edit_others_posts`, `publish_pages`, `upload_files`, and `unfiltered_html` — by naming a revision whose `_elementor_data` contains an elevated role an administrator previously saved and later reverted on a page bearing the Login/Register widget. Successful exploitation requires that the site has "Anyone can register" enabled and that an administrator has at some point saved and then reverted a non-default "New User Role" on an affected page.
