The Easy Form Builder plugin for WordPress, developed by WhiteStudio, suffers from a missing authorization vulnerability identified as CVE-2025-14067. This vulnerability exists in all versions up to and including 3.9.3. The issue stems from a logic error in the capability check performed on several AJAX actions that handle form response data. Specifically, the authorization check incorrectly uses a logical AND (&&) operator instead of an OR (||), which results in insufficient verification of user permissions. Consequently, any authenticated user with at least Subscriber-level access can exploit this flaw to retrieve sensitive data stored by the plugin, such as form submissions, messages, administrative replies, and user details. The vulnerability does not require elevated privileges beyond Subscriber, nor does it require additional user interaction once authenticated. The CVSS v3.1 base score is 5.3 (medium severity), reflecting the network attack vector, low complexity, no privileges required, and no user interaction needed. The impact is limited to confidentiality loss, with no effect on integrity or availability. No known public exploits or patches have been reported as of the publication date. This vulnerability highlights the importance of proper authorization checks in WordPress plugins, especially those handling sensitive user data via AJAX endpoints.

The primary impact of CVE-2025-14067 is unauthorized disclosure of sensitive form data, which may include personally identifiable information (PII), user messages, and administrative replies. This can lead to privacy violations, data leakage, and potential compliance issues for organizations subject to data protection regulations such as GDPR or CCPA. Attackers with Subscriber-level access—often easy to obtain through compromised or created accounts—can exploit this flaw to harvest sensitive data without needing elevated privileges. While the vulnerability does not affect data integrity or system availability, the confidentiality breach can damage organizational reputation and trust. For organizations relying on the Easy Form Builder plugin for critical data collection, this vulnerability could expose sensitive customer or internal communications. Additionally, attackers might use the disclosed information for further targeted attacks such as phishing or social engineering. The absence of known exploits reduces immediate risk, but the ease of exploitation and widespread use of WordPress make this a significant concern.

To mitigate CVE-2025-14067, organizations should first check if an updated version of the Easy Form Builder plugin is available that addresses the authorization logic error and apply it promptly. In the absence of an official patch, administrators should consider disabling the plugin or restricting access to authenticated users with Subscriber-level permissions or higher until a fix is released. Implementing web application firewall (WAF) rules to monitor and block suspicious AJAX requests targeting the plugin’s endpoints can provide temporary protection. Reviewing and tightening user role assignments to minimize unnecessary Subscriber-level accounts reduces the attack surface. Additionally, conducting a thorough audit of form data access logs may help detect exploitation attempts. Plugin developers and site administrators should also verify that all AJAX actions enforce proper capability checks using correct logical operators. Finally, educating users about the risks of account compromise and enforcing strong authentication mechanisms (e.g., MFA) can help prevent attackers from gaining the initial access needed to exploit this vulnerability.
