Vulnerability information

On March 22, 2023, Elementor Pro released version 3.11.7 of its plugin which fixes a critical Elementor Pro vulnerability that in combination with the WooCommerce plugin running on the site allows any authenticated user (such as the subscriber or customer user role) to update any WordPress setting on the site. This is done through an AJAX action of Elementor Pro that does not have proper privilege control in place. Versions 3.11.6 and below are affected by this vulnerability.

This makes it possible for a malicious user to turn on the registration page (if disabled) and set the default user role to administrator so they can create an account that instantly has administrator privileges. After this, they are likely to redirect the site to another malicious domain or upload a malicious plugin or backdoor to exploit the site further.
