CVE-2026-9018: Easy Elements WordPress Plugin Privilege Escalation
The Easy Elements for Elementor – Addons & Website Templates plugin for WordPress, in all versions up to and including 1.4.5, is vulnerable to a critical privilege escalation. The National Vulnerability Database (NVD) reports this flaw, tracked as CVE-2026-9018, stems from the easyel_handle_register() function’s wp_ajax_nopriv_eel_register AJAX handler.
This handler improperly processes the attacker-controlled custom_meta POST array. Instead of validating keys against a whitelist or blocklist, it directly writes every supplied key-value pair to the newly created user’s meta via update_user_meta(). This design flaw allows an unauthenticated attacker to overwrite the wp_capabilities user meta key after wp_insert_user() has already assigned a safe, default role.
Exploitation is straightforward: if user registration is enabled and the Login/Register widget is exposed on any page, an attacker can register a new account and supply custom_meta[wp_capabilities][administrator]=1 to gain full administrator privileges. The necessary easy_elements_nonce token is readily available in the page DOM via a simple GET request. NVD assigns this vulnerability a CVSS score of 8.8 (HIGH).
What This Means For You
- If your WordPress site uses the Easy Elements for Elementor plugin and allows user registration, you are exposed. Unauthenticated attackers can become site administrators in minutes. Immediately disable user registration if it's not strictly necessary. If it is, or if you use the affected plugin, patch to a fixed version beyond 1.4.5 without delay. Audit logs for any newly created administrator accounts, especially those with unusual registration times or IP addresses.
