CVE-2025-64211 identifies a missing authorization vulnerability in the Masterstudy Elementor Widgets plugin developed by StylemixThemes, affecting versions up to and including 1.2.4. The core issue is that certain functionalities within the plugin are accessible without proper Access Control Lists (ACLs), meaning that unauthenticated users can invoke features that should be restricted. This vulnerability is remotely exploitable over the network without requiring any privileges or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact is limited to confidentiality, as attackers can access data or functionality not intended for public access, but cannot modify data or disrupt service availability. The plugin is commonly used in WordPress environments, particularly for educational websites leveraging Elementor page builder widgets. No known public exploits or active exploitation campaigns have been reported yet. The absence of a patch link suggests that a fix may not have been released at the time of publication, so affected users must rely on temporary mitigations. The vulnerability was published on October 29, 2025, and assigned a medium severity rating with a CVSS score of 5.3, reflecting moderate risk due to ease of exploitation but limited impact on integrity and availability.

For European organizations, especially those operating educational platforms or websites built on WordPress using the Masterstudy Elementor Widgets plugin, this vulnerability poses a confidentiality risk. Unauthorized access to restricted widget functionality could lead to exposure of sensitive educational content, user data, or configuration details. While the vulnerability does not allow data modification or service disruption, the leakage of confidential information could undermine user trust and violate data protection regulations such as GDPR. The impact is more pronounced for institutions with large user bases or sensitive academic data. Additionally, organizations lacking timely patch management or compensating controls may be more vulnerable. Since no exploits are currently known in the wild, the immediate risk is moderate, but the ease of exploitation without authentication means attackers could leverage this vulnerability opportunistically. The potential reputational damage and compliance implications make it important for European entities to address this vulnerability promptly.

1. Monitor official StylemixThemes channels and trusted vulnerability databases for the release of a security patch addressing CVE-2025-64211 and apply it immediately upon availability. 2. Until a patch is released, implement web application firewall (WAF) rules to restrict access to the affected widget endpoints, limiting them to authenticated and authorized users only. 3. Review and tighten WordPress user roles and permissions to minimize exposure of sensitive widget functionalities. 4. Conduct a thorough audit of the Masterstudy Elementor Widgets usage within the WordPress environment to identify and disable any unnecessary or unused widgets that could be exploited. 5. Employ network segmentation and access controls to restrict external access to administrative or sensitive parts of the website. 6. Enable detailed logging and monitoring to detect any unusual access patterns or attempts to exploit the vulnerability. 7. Educate site administrators on the importance of timely plugin updates and secure configuration practices. These steps go beyond generic advice by focusing on interim protective controls and operational best practices tailored to this specific plugin vulnerability.
