CVE-2025-14072 is an authentication bypass vulnerability identified in the Ninja Forms WordPress plugin versions prior to 3.13.3. The flaw stems from improper authentication controls (CWE-287) in the plugin's REST API implementation, which allows unauthenticated attackers to generate valid access tokens. These tokens grant unauthorized access to read form submissions, potentially exposing sensitive user data collected via forms on affected websites. The vulnerability requires no privileges or user interaction and can be exploited remotely over the network. The CVSS 3.1 base score of 5.3 indicates a medium severity, primarily due to the confidentiality impact without affecting integrity or availability. No known exploits have been reported in the wild, but the ease of exploitation and the sensitive nature of form data make this a noteworthy risk. The vulnerability highlights a critical lapse in access control mechanisms within the REST API endpoints of Ninja Forms, which are widely used for form management in WordPress environments. Organizations using Ninja Forms should urgently update to version 3.13.3 or later, which addresses this authentication flaw. Additionally, monitoring REST API access logs and implementing strict access controls can help mitigate potential exploitation attempts.

The primary impact of CVE-2025-14072 is the unauthorized disclosure of form submission data, which may include personally identifiable information (PII), payment details, or other sensitive inputs collected via Ninja Forms. For European organizations, this raises significant privacy and compliance concerns, particularly under GDPR regulations that mandate strict protection of personal data. Unauthorized access to form data can lead to data breaches, reputational damage, and potential regulatory fines. Since the vulnerability does not affect data integrity or availability, the risk is confined to confidentiality breaches. However, the ease of exploitation without authentication or user interaction increases the likelihood of opportunistic attacks. Organizations relying on Ninja Forms for customer interactions, surveys, or transactional data collection are at risk of exposing sensitive information to malicious actors. This can undermine trust and lead to secondary attacks such as phishing or identity theft. The medium severity rating suggests that while the threat is serious, it is not critical, but timely remediation is essential to prevent data leakage.

1. Immediately update the Ninja Forms plugin to version 3.13.3 or later, where this vulnerability is patched. 2. Restrict REST API access to trusted users or IP ranges using WordPress security plugins or server-level controls to limit exposure. 3. Implement web application firewalls (WAFs) with rules to detect and block suspicious REST API token generation attempts. 4. Regularly audit and monitor REST API logs for unusual access patterns or token generation activities. 5. Enforce the principle of least privilege on WordPress user roles to minimize potential damage if credentials are compromised. 6. Educate site administrators on the importance of timely plugin updates and secure configuration practices. 7. Consider disabling REST API endpoints related to Ninja Forms if not required for site functionality. 8. Conduct periodic security assessments and penetration testing focused on REST API endpoints to identify similar weaknesses.
