CVE-2025-64211 is a security vulnerability identified in the StylemixThemes Masterstudy Elementor Widgets plugin for WordPress, affecting versions up to and including 1.2.4. The core issue is a missing authorization check, meaning that certain functionalities within the plugin are accessible without proper verification of user permissions. This lack of access control allows unauthorized users to invoke functions that should be restricted, potentially leading to unauthorized data access, modification, or other malicious actions within the context of the affected WordPress site. The vulnerability does not require prior authentication, which significantly lowers the barrier for exploitation. Although no public exploits have been reported at this time, the exposure of educational or e-learning platforms using this plugin could be significant. The plugin is commonly used to enhance Elementor-based WordPress sites with educational widgets, making it a target for attackers seeking to compromise educational content or user data. The absence of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed, but the nature of missing authorization typically results in a high severity rating due to the direct impact on access control mechanisms. The vulnerability was published on October 29, 2025, by Patchstack, and no official patches or fixes have been linked yet, emphasizing the need for vigilance and interim protective measures.

For European organizations, especially those operating e-learning platforms or educational websites using WordPress with the Masterstudy Elementor Widgets plugin, this vulnerability poses a significant risk. Unauthorized access to restricted functionalities could lead to data breaches involving sensitive educational content, user information, or administrative controls. This could result in reputational damage, regulatory non-compliance (e.g., GDPR violations), and operational disruption. The ease of exploitation without authentication increases the likelihood of attacks, potentially enabling attackers to manipulate course content, access private user data, or disrupt service availability. Given the widespread use of WordPress and Elementor in Europe, particularly in countries with strong digital education sectors, the impact could be broad. Additionally, compromised educational platforms could be leveraged as footholds for further network intrusion or phishing campaigns targeting students and staff.

Immediate mitigation should focus on monitoring and restricting access to the affected plugin's functionalities. Organizations should implement strict web application firewall (WAF) rules to detect and block unauthorized requests targeting Masterstudy Elementor Widgets endpoints. Until an official patch is released, administrators can disable or limit the plugin's use on critical systems or restrict access to trusted users only. Regularly audit user roles and permissions within WordPress to ensure no excessive privileges are granted. Employ security plugins that enhance access control and monitor for anomalous activities. Additionally, maintain up-to-date backups to enable quick recovery if exploitation occurs. Once a patch is available, prioritize its deployment across all affected systems. Organizations should also educate their IT teams about this vulnerability to ensure rapid response and incident handling.
