The Essential Addons for Elementor plugin for WordPress is vulnerable to privilege escalation in versions up to and including 5.8.8 due to a lack of restrictions on who can add a registration form and a custom registration role to an Elementor created page. This makes it possible for attackers with access to the Elementor page builder to create a new registration form that defaults to the user role being set to administrator and subsequently register as an administrative user. Note that this is difficult to exploit without publishing capabilities and appears to be a regression, as an identical issue was patched in version 4.6.5.
