CVE-2025-11007: CE21COM CE21 Suite

Critical severity, CVSS 9.8. EPSS: 0.5% chance of exploitation in the next 30 days.

The CE21 Suite plugin for WordPress is vulnerable to unauthorized plugin settings update due to a missing capability check on the wp_ajax_nopriv_ce21_single_sign_on_save_api_settings AJAX action in versions 2.2.1 to 2.3.1. This makes it possible for unauthenticated attackers to update the plugin's API settings including a secret key used for authentication. This allows unauthenticated attackers to create new admin accounts on an affected site.

Affected products

• CE21COM CE21 Suite: from 2.2.1, up to and including 2.3.1
