CVE-2026-0920 is a critical security vulnerability identified in the LA-Studio Element Kit for Elementor, a popular WordPress plugin used to enhance Elementor page builder capabilities. The vulnerability stems from improper privilege management (CWE-269) in the plugin's 'ajax_register_handle' function, which handles user registration requests. Specifically, this function does not properly restrict the 'lakit_bkrole' parameter, allowing an unauthenticated attacker to specify arbitrary user roles during registration. By exploiting this flaw, an attacker can create a new user account with administrative privileges without any authentication or user interaction. This effectively grants full control over the affected WordPress site, enabling the attacker to modify content, install malicious plugins, exfiltrate data, or pivot to other parts of the network. The vulnerability affects all versions of the plugin up to and including 1.5.6.3. The CVSS v3.1 base score is 9.8 (critical), reflecting the high impact on confidentiality, integrity, and availability, combined with the ease of remote exploitation without authentication. No patches or official fixes have been released at the time of publication, and no active exploitation has been reported. However, the severity and simplicity of exploitation make this a high-risk vulnerability for WordPress sites using this plugin. The vulnerability is particularly dangerous because it bypasses normal user role assignment controls, a fundamental security mechanism in WordPress. Attackers leveraging this flaw can gain persistent administrative access, making detection and remediation more challenging. Organizations relying on this plugin should urgently assess their exposure and implement mitigations to prevent exploitation.

For European organizations, the impact of CVE-2026-0920 is substantial. Successful exploitation results in full administrative control over WordPress sites, which are commonly used for corporate websites, intranets, and customer portals. This can lead to unauthorized data access, defacement, malware distribution, and use of compromised sites as footholds for further network intrusion. Confidential business information and customer data could be exposed or altered, causing regulatory compliance violations under GDPR and other data protection laws. The availability of affected services may be disrupted, impacting business operations and customer trust. Given the critical nature of the vulnerability and the widespread use of WordPress and Elementor in Europe, organizations face a high risk of targeted attacks and automated exploitation attempts. The lack of authentication and user interaction requirements lowers the barrier for attackers, increasing the likelihood of exploitation. Additionally, compromised sites may be used to launch phishing campaigns or distribute ransomware, amplifying the overall threat landscape for European entities.

1. Immediately disable or uninstall the LA-Studio Element Kit for Elementor plugin until a security patch is released. 2. If disabling the plugin is not feasible, restrict access to the 'ajax_register_handle' endpoint via web application firewall (WAF) rules or server-level access controls to block unauthenticated requests. 3. Monitor WordPress user accounts for any unauthorized administrative users and remove suspicious accounts promptly. 4. Implement strict logging and alerting on user registration activities, especially those involving administrative roles. 5. Harden WordPress installations by enforcing least privilege principles and regularly reviewing user roles and permissions. 6. Keep all WordPress core, themes, and plugins updated to the latest versions once a patch for this vulnerability is available. 7. Conduct regular security audits and vulnerability scans focused on WordPress environments. 8. Educate site administrators about this vulnerability and encourage immediate action to mitigate risks. 9. Consider deploying multi-factor authentication (MFA) for all administrative accounts to reduce the impact of compromised credentials. 10. Backup WordPress sites regularly and verify backup integrity to enable rapid recovery in case of compromise.
