CVE-2025-49907 is a missing authorization vulnerability identified in the RealMag777 MDTF (Meta Data Filter and Taxonomy Filter) WordPress plugin, affecting versions up to and including 1.3.3.9. The vulnerability arises from incorrectly configured access control security levels within the plugin, allowing users with low privileges (PR:L) to access certain data or functionality without proper authorization. The attack vector is network-based (AV:N), and no user interaction is required (UI:N). The vulnerability does not affect the integrity or availability of the system but results in limited confidentiality impact (C:L, I:N, A:N). This means an attacker could potentially view data they should not have access to but cannot modify or disrupt the system. The CVSS score of 4.3 reflects this medium severity. There are no known exploits in the wild at the time of publication, and no official patches have been linked yet. The vulnerability is particularly relevant for WordPress sites using the MDTF plugin for filtering metadata and taxonomies, which is common in content-heavy or e-commerce websites. The missing authorization flaw likely stems from insufficient validation of user permissions before granting access to certain plugin features or data endpoints. This could allow an authenticated low-privilege user, such as a subscriber or contributor, to access restricted information or functionality intended for higher-privileged roles. The issue was reserved in June 2025 and published in October 2025, indicating recent discovery and disclosure.

For European organizations, the primary impact of CVE-2025-49907 is unauthorized data exposure within WordPress sites using the MDTF plugin. This could lead to leakage of sensitive metadata or taxonomy-related information, which might include product details, user-generated content, or internal categorization data. Although the vulnerability does not allow data modification or service disruption, unauthorized access to confidential information can undermine trust, violate data protection regulations such as GDPR, and potentially aid further targeted attacks. Organizations relying on MDTF for filtering and displaying content dynamically may inadvertently expose internal data to low-privilege users or attackers who have gained limited access. This risk is heightened for sectors handling sensitive or regulated data, such as e-commerce, publishing, or governmental websites. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits post-disclosure. The medium severity reflects a moderate risk level that should be addressed promptly to prevent escalation or combined attacks leveraging this vulnerability.

1. Monitor official RealMag777 channels and trusted vulnerability databases for the release of a security patch addressing CVE-2025-49907 and apply it immediately upon availability. 2. Until a patch is available, implement strict access control policies at the web server or application firewall level to restrict access to MDTF plugin endpoints only to trusted, higher-privileged users. 3. Conduct an audit of user roles and permissions within WordPress to ensure that low-privilege users do not have unnecessary access to sensitive plugin features or data. 4. Employ security plugins or custom code to enforce additional authorization checks on MDTF-related requests, effectively compensating for the plugin’s missing authorization. 5. Regularly review and monitor web server logs and WordPress activity logs for unusual access patterns or attempts to exploit the plugin. 6. Educate site administrators and developers about the risks of missing authorization vulnerabilities and the importance of principle of least privilege in user role assignments. 7. Consider isolating critical WordPress instances or sensitive content behind VPNs or IP whitelisting where feasible to reduce exposure. 8. Maintain regular backups of WordPress sites and databases to enable recovery in case of exploitation or related incidents.
