CVE-2025-67579 is a vulnerability identified in the vanquish User Extra Fields WordPress plugin, specifically affecting versions up to 16.8. The core issue is a missing authorization control, which means that the plugin fails to properly verify whether a user has the necessary permissions before allowing access to certain user extra fields. This misconfiguration allows unauthenticated remote attackers to access sensitive user data that should otherwise be protected. The vulnerability is categorized under access control weaknesses, where the security levels are incorrectly configured, leading to unauthorized data exposure. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N), the attack vector is network-based with low attack complexity, no privileges required, and no user interaction needed. The impact is limited to confidentiality, with no effect on data integrity or system availability. Although no known exploits have been reported in the wild, the vulnerability poses a risk to any WordPress site using the affected plugin, especially those handling sensitive user information. The absence of patch links suggests that a fix may not yet be publicly available, emphasizing the need for vigilance and interim protective measures.

For European organizations, the primary impact of CVE-2025-67579 is unauthorized disclosure of user data managed through the vanquish User Extra Fields plugin. This could lead to privacy violations, non-compliance with GDPR regulations, and reputational damage. Since the vulnerability does not affect data integrity or availability, operational disruptions are unlikely. However, the exposure of personal or sensitive user information can have legal and financial consequences under European data protection laws. Organizations relying on WordPress for customer-facing or internal portals that utilize this plugin are at risk of data leakage. The ease of exploitation without authentication increases the threat level, especially for publicly accessible websites. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future attacks. Overall, the vulnerability could undermine trust in affected services and necessitate incident response efforts if exploited.

1. Monitor official vanquish and WordPress plugin repositories for security updates and apply patches immediately once available. 2. Conduct a thorough audit of access control configurations related to the User Extra Fields plugin to identify and remediate any misconfigurations. 3. Restrict access to WordPress administrative and user management interfaces using network-level controls such as IP whitelisting or VPN access. 4. Implement Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin endpoints. 5. Regularly review user data exposure and logs for unusual access patterns that may indicate exploitation attempts. 6. Consider temporarily disabling or replacing the plugin with alternatives that have verified secure access controls until a patch is released. 7. Educate site administrators about the risks of unauthorized access and the importance of timely updates and configuration management.
