CVE-2025-64210 is a vulnerability identified in the StylemixThemes Masterstudy Elementor Widgets plugin for WordPress, specifically in versions up to and including 1.2.4. The root cause is a missing authorization mechanism, meaning the plugin fails to properly verify whether a user has the necessary permissions before allowing certain actions. This incorrect access control can be exploited by an attacker who has low-level privileges (PR:L) to perform unauthorized operations that could lead to limited confidentiality and integrity breaches. The vulnerability does not require user interaction (UI:N) and can be exploited remotely over the network (AV:N). The CVSS v3.1 base score is 5.4, indicating a medium severity level. The scope is unchanged (S:U), meaning the impact is confined to the vulnerable component itself. Although no public exploits are currently known, the vulnerability could be leveraged to access or modify sensitive data within the affected WordPress environment. The plugin is commonly used in educational websites built with Elementor, which may increase the risk profile for organizations in the education sector. The lack of a patch link suggests that a fix may not yet be publicly available, emphasizing the need for vigilance and interim mitigations.

For European organizations, especially those in the education sector or those heavily reliant on WordPress with Elementor and StylemixThemes plugins, this vulnerability poses a risk of unauthorized data access and modification. Confidentiality could be compromised if sensitive educational content or user data is exposed. Integrity risks arise if attackers alter content or configurations, potentially undermining trust and operational reliability. Although availability is not directly impacted, unauthorized changes could indirectly disrupt services or user experience. The medium severity score reflects a moderate risk, but the ease of exploitation by low-privilege users without user interaction increases the threat potential. Organizations with public-facing WordPress sites using this plugin are particularly vulnerable to remote exploitation attempts. The absence of known exploits in the wild currently limits immediate widespread impact but does not preclude targeted attacks. European entities must consider the regulatory implications of data breaches under GDPR, which could lead to significant compliance penalties if personal data is compromised.

1. Monitor official StylemixThemes channels and Patchstack for the release of a security patch and apply it immediately upon availability. 2. In the interim, restrict access to the WordPress admin and plugin management interfaces to trusted users only, employing strong authentication and role-based access controls. 3. Implement web application firewall (WAF) rules to detect and block suspicious requests targeting the vulnerable plugin endpoints. 4. Conduct regular audits of user privileges to ensure no unnecessary permissions are granted, minimizing the risk of exploitation by low-privilege users. 5. Enable detailed logging and monitoring of plugin-related activities to detect unauthorized access or modifications promptly. 6. Consider temporarily disabling or replacing the Masterstudy Elementor Widgets plugin if feasible until a patch is available. 7. Educate site administrators about the risks and signs of exploitation related to this vulnerability. 8. Review and tighten overall WordPress security posture, including timely updates of all plugins, themes, and core software.
