CVE-2025-64210 identifies a missing authorization vulnerability in the StylemixThemes Masterstudy Elementor Widgets plugin for WordPress, specifically affecting versions up to 1.2.4. The vulnerability arises from incorrectly configured access control security levels, which fail to properly verify whether a user has the necessary permissions to perform certain actions within the plugin. This missing authorization can allow an attacker to bypass intended restrictions, potentially enabling unauthorized operations such as modifying widget settings, injecting malicious content, or accessing sensitive data managed by the plugin. The plugin is commonly used to enhance Elementor-based WordPress sites, particularly in educational contexts where Masterstudy themes are popular. Although no public exploits have been reported, the vulnerability's nature suggests that exploitation could be straightforward if an attacker can interact with the plugin's endpoints. The absence of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed, but the technical details imply significant risk. The vulnerability does not require user interaction, and authentication requirements are unclear but likely minimal given the missing authorization context. This flaw compromises the integrity and confidentiality of affected systems and could lead to further exploitation if chained with other vulnerabilities.

For European organizations, especially those operating educational websites or e-learning platforms using WordPress with the Masterstudy Elementor Widgets plugin, this vulnerability could lead to unauthorized changes to website content, exposure of sensitive educational materials, or insertion of malicious code. This can damage organizational reputation, lead to data breaches involving student or staff information, and disrupt online learning services. The impact extends to integrity and confidentiality, as attackers might alter course content or access restricted data. Availability impact is less direct but possible if attackers leverage the vulnerability to deface or disable site functionality. Given the widespread use of WordPress in Europe and the popularity of Elementor and educational themes, the vulnerability could affect a broad range of institutions, from universities to private training providers. The lack of known exploits currently limits immediate risk, but the vulnerability's presence in a critical plugin demands prompt attention to prevent future attacks.

Organizations should immediately inventory their WordPress installations to identify the presence of the Masterstudy Elementor Widgets plugin and verify the version in use. Until an official patch is released, restrict access to plugin management interfaces via web application firewalls (WAFs) or IP whitelisting to limit exposure. Implement strict role-based access controls within WordPress to ensure only trusted administrators can modify plugin settings. Monitor logs for unusual activity related to the plugin endpoints, such as unauthorized POST requests or configuration changes. Regularly update WordPress core, themes, and plugins to incorporate security patches promptly. Consider deploying security plugins that can detect and block unauthorized access attempts. Engage with the vendor or security community for updates and apply patches as soon as they become available. Additionally, conduct security awareness training for administrators to recognize potential exploitation attempts.
