CVE-2025-62964 is a missing authorization vulnerability identified in the RealMag777 MDTF WordPress plugin, specifically the Meta Data Filter and Taxonomy Filter component. This vulnerability arises from incorrectly configured access control security levels, allowing attackers with low privileges (PR:L) to bypass authorization checks and perform unauthorized actions. The vulnerability affects all versions up to and including 1.3.4. The CVSS 3.1 score of 8.1 indicates a high severity, with an attack vector over the network (AV:N), low attack complexity (AC:L), requiring privileges (PR:L) but no user interaction (UI:N). The scope remains unchanged (S:U), but the impact on confidentiality (C:H) and integrity (I:H) is high, while availability (A:N) is unaffected. This means an attacker with some level of access can escalate privileges or access sensitive data without proper authorization, potentially leading to data leakage or unauthorized modifications. No public exploits have been reported yet, but the vulnerability's nature makes it a significant risk for WordPress sites using this plugin. The lack of a patch link suggests that a fix may not yet be available, emphasizing the need for immediate mitigation steps.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of data processed or filtered by the MDTF plugin. Organizations relying on WordPress for content management, e-commerce, or internal data filtering could face unauthorized data exposure or manipulation. This could lead to data breaches involving personal data protected under GDPR, resulting in regulatory penalties and reputational damage. The absence of availability impact means service disruption is unlikely, but unauthorized data access or modification could compromise business operations and trust. Attackers exploiting this vulnerability could gain unauthorized insights into filtered metadata or taxonomies, potentially exposing sensitive business intelligence or user data. The threat is particularly relevant for sectors with high WordPress adoption, such as media, retail, and public sector websites across Europe.

1. Monitor RealMag777’s official channels for patches addressing CVE-2025-62964 and apply updates immediately upon release. 2. Until a patch is available, restrict access to the MDTF plugin’s administrative and filtering functionalities to trusted users only, using WordPress role management and access control plugins. 3. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting MDTF endpoints. 4. Conduct thorough audits of user privileges to ensure minimal necessary access, reducing the risk posed by low-privilege attackers. 5. Enable detailed logging and monitoring of plugin-related activities to detect unauthorized access attempts early. 6. Consider temporarily disabling the MDTF plugin if it is not critical to operations or if risk tolerance is low. 7. Educate site administrators about the vulnerability and the importance of access control hygiene. 8. Review and harden WordPress security configurations, including limiting plugin installations and enforcing strong authentication mechanisms.
