CVE-2025-64211 identifies a missing authorization vulnerability in the Masterstudy Elementor Widgets plugin developed by StylemixThemes, affecting all versions up to and including 1.2.4. The vulnerability arises because certain functionalities within the plugin are not properly constrained by Access Control Lists (ACLs), allowing unauthenticated remote attackers to invoke these functions without the necessary permissions. This can lead to unauthorized access to plugin features or data that should be restricted. The 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 loss, with no direct effect on data integrity or system availability. No known public exploits or patches have been reported at the time of publication. The plugin is commonly used in WordPress environments, particularly for educational websites leveraging Elementor page builder widgets. The lack of authorization checks suggests a design or implementation oversight in the plugin's access control mechanisms, which could be exploited to extract sensitive information or perform unauthorized read operations within the plugin's scope. Since the vulnerability does not require authentication, it poses a risk to any publicly accessible WordPress site using the affected plugin version.

For European organizations, the primary impact is unauthorized disclosure of potentially sensitive information managed or displayed by the Masterstudy Elementor Widgets plugin. Educational institutions, e-learning platforms, and training providers using this plugin could face data confidentiality breaches, which may include user data or proprietary course content. Although the vulnerability does not allow modification or deletion of data, the exposure of confidential information could lead to reputational damage, regulatory non-compliance (e.g., GDPR violations), and loss of user trust. The ease of exploitation without authentication increases the risk, especially for publicly accessible websites. However, the absence of known exploits and the medium severity rating suggest that the threat is moderate but should not be ignored. Organizations relying heavily on WordPress and Elementor-based educational themes are more vulnerable, and the impact could be amplified if combined with other vulnerabilities or misconfigurations.

1. Monitor official StylemixThemes channels and trusted vulnerability databases for the release of patches addressing CVE-2025-64211 and apply updates promptly. 2. Until patches are available, restrict access to the WordPress admin interface and plugin functionalities by IP whitelisting or VPN access to reduce exposure. 3. Implement Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the Masterstudy Elementor Widgets plugin endpoints. 4. Conduct a thorough audit of user roles and permissions within WordPress to ensure that only trusted administrators have plugin management rights. 5. Consider temporarily disabling or removing the plugin if it is not critical to operations or if the risk outweighs the benefit. 6. Employ security plugins that can monitor and alert on unauthorized access attempts or anomalous plugin behavior. 7. Educate site administrators about the risks of using outdated plugins and the importance of timely updates. 8. Review server and application logs regularly for signs of exploitation attempts related to this vulnerability.
