CVE-2025-64210 identifies a missing authorization vulnerability in the StylemixThemes Masterstudy Elementor Widgets plugin for WordPress, specifically affecting versions up to and including 1.2.4. The vulnerability arises from incorrectly configured access control mechanisms that fail to properly verify whether a user has the necessary permissions to perform certain actions within the plugin. This flaw enables attackers with limited privileges (PR:L) to remotely exploit the plugin without requiring user interaction (UI:N), potentially leading to unauthorized disclosure of information (confidentiality impact) and unauthorized modification of data (integrity impact). The CVSS 3.1 base score of 5.4 reflects a medium severity level, with network attack vector (AV:N), low attack complexity (AC:L), and no impact on availability (A:N). The scope remains unchanged (S:U), meaning the vulnerability affects only the vulnerable component itself. Although no known exploits have been reported in the wild, the vulnerability presents a risk to WordPress sites using this plugin, particularly those in educational or e-learning contexts where Masterstudy Elementor Widgets are commonly deployed. The lack of patch links suggests that a fix may not yet be publicly available, emphasizing the need for proactive mitigation. The vulnerability's exploitation could allow attackers to bypass intended access restrictions, potentially exposing sensitive content or altering widget behavior, undermining the integrity of the affected sites.

For European organizations, this vulnerability poses a moderate risk primarily to educational institutions, e-learning providers, and businesses utilizing WordPress sites with the Masterstudy Elementor Widgets plugin. Unauthorized access could lead to leakage of sensitive educational content, user data, or administrative information, impacting confidentiality. Integrity could be compromised if attackers manipulate widget content or configurations, potentially misleading users or disrupting learning processes. Although availability is not directly affected, reputational damage and loss of trust could result from exploitation. Organizations relying heavily on WordPress for their digital presence, especially in sectors with strict data protection regulations like GDPR, must consider the compliance implications of any data exposure. The medium severity suggests that while the threat is not critical, it warrants timely attention to prevent escalation or chaining with other vulnerabilities.

1. Monitor official StylemixThemes channels and security advisories for patches addressing CVE-2025-64210 and apply updates promptly once available. 2. Until patches are released, restrict access to the Masterstudy Elementor Widgets plugin by limiting user roles and permissions strictly to trusted administrators. 3. Implement robust role-based access control (RBAC) within WordPress to ensure that only authorized users can interact with the plugin’s features. 4. Conduct regular audits of user permissions and plugin configurations to detect and remediate any misconfigurations. 5. Employ web application firewalls (WAF) with custom rules to detect and block suspicious requests targeting the plugin endpoints. 6. Enable detailed logging and monitoring of plugin-related activities to identify potential exploitation attempts early. 7. Educate site administrators about the risks of unauthorized access and the importance of maintaining least privilege principles. 8. Consider isolating or sandboxing the plugin environment if feasible to minimize the impact of potential exploitation.
