CVE-2025-62964 is a missing authorization vulnerability identified in the RealMag777 MDTF WordPress plugin, specifically the wp-meta-data-filter-and-taxonomy-filter component, affecting all versions up to and including 1.3.4. The vulnerability arises from incorrectly configured access control security levels, allowing an attacker with low privileges (PR:L) to bypass authorization checks and perform unauthorized actions remotely over the network (AV:N) without requiring user interaction (UI:N). The vulnerability impacts confidentiality and integrity (C:H/I:H) but does not affect availability (A:N). This means attackers can potentially access or modify sensitive data or configurations within the WordPress environment, leading to data breaches or site defacement. The plugin is commonly used to filter metadata and taxonomy terms in WordPress sites, which may expose sensitive filtering or categorization data. Although no known exploits are currently reported in the wild, the high CVSS score (8.1) indicates a significant risk if weaponized. The vulnerability was reserved on 2025-10-24 and published on 2025-10-27, with no patch links currently available, indicating that mitigation options may be limited until vendor updates are released. The issue is critical for organizations relying on this plugin for content management and filtering, especially those handling regulated or sensitive information.

For European organizations, the impact of CVE-2025-62964 can be substantial. Unauthorized access to WordPress sites using the RealMag777 MDTF plugin can lead to exposure or modification of sensitive data, undermining confidentiality and integrity. This can result in data breaches, loss of customer trust, regulatory non-compliance (e.g., GDPR violations), and potential financial penalties. The vulnerability could also be leveraged as a foothold for further attacks within the network, including lateral movement or deployment of malware. Organizations in sectors such as finance, healthcare, government, and e-commerce, which often use WordPress for public-facing or internal portals, are particularly at risk. The lack of availability impact reduces the risk of denial-of-service, but the high confidentiality and integrity impact still make this a critical threat. The ease of exploitation over the network with low privileges and no user interaction increases the likelihood of successful attacks if the vulnerability is not promptly addressed.

1. Monitor RealMag777's official channels for patches addressing CVE-2025-62964 and apply updates immediately upon release. 2. Until patches are available, restrict access to the WordPress admin and plugin management interfaces to trusted IP addresses using firewall rules or VPNs. 3. Implement strict role-based access controls within WordPress to minimize the number of users with privileges that could be exploited. 4. Conduct regular audits of user permissions and plugin configurations to detect misconfigurations. 5. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the MDTF plugin endpoints. 6. Enable detailed logging and monitor for unusual activity related to metadata filtering or taxonomy operations. 7. Consider temporarily disabling the MDTF plugin if it is not critical to operations until a patch is available. 8. Educate site administrators about the risks and signs of exploitation related to this vulnerability. 9. Use security plugins that can detect unauthorized changes or access attempts within WordPress environments.
