Elementor 4.3.0 - 4.3.1 - Privilege Escalation via CSRF

Description

The plugin is vulnerable to Cross-Site Request Forgery due to missing or incorrect nonce validation on the is_own_route_request function. This makes it possible for unauthenticated attackers to perform any authenticated REST action available to the victim's role, including creating administrator-level accounts, modifying site options, or deleting content, while the victim's cookie session remains fully authenticated via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
