AI-suggested
To mitigate CVE-2025-11007, organizations should immediately audit their WordPress installations for the presence of the CE21 Suite plugin versions 2.2.1 to 2.3.1 and disable or remove the plugin if a patch is not yet available. Monitor official vendor channels for security updates and apply patches as soon as they are released. In the interim, restrict access to the wp-admin/admin-ajax.php endpoint via web application firewall (WAF) rules or server-level access controls to block unauthenticated requests targeting the wp_ajax_nopriv_ce21_single_sign_on_save_api_settings action. Implement strict monitoring and alerting for suspicious AJAX requests and unexpected changes in plugin settings. Conduct regular audits of WordPress user accounts to detect unauthorized administrator creation. Employ multi-factor authentication (MFA) for all admin accounts to reduce the risk of account misuse. Backup site data frequently and maintain incident response plans tailored to WordPress compromises. Finally, consider isolating critical WordPress instances behind VPNs or IP whitelisting where feasible to limit exposure.
Description
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.
