CVE-2025-14072 is a security vulnerability classified under CWE-287 (Improper Authentication) affecting the Ninja Forms WordPress plugin prior to version 3.13.3. The vulnerability arises because the plugin's REST API improperly allows unauthenticated users to generate valid access tokens. These tokens can then be used to access and read form submissions stored by the plugin. Since form submissions often contain sensitive information such as personal data, contact details, or other confidential inputs, unauthorized access can lead to data leakage and privacy violations. The flaw does not require any authentication or user interaction, making it exploitable remotely and potentially at scale. The vulnerability was reserved in December 2025 and published in January 2026, with no CVSS score assigned yet and no known exploits reported in the wild. The lack of a patch link suggests that users must update to at least version 3.13.3, where the issue is presumably fixed. The vulnerability impacts the confidentiality of data collected via Ninja Forms and could be leveraged for further attacks if sensitive data is exposed. The REST API's improper authentication mechanism is the root cause, allowing token generation without verifying user credentials or permissions.

For European organizations, the impact of CVE-2025-14072 can be significant, especially for those relying on Ninja Forms to collect user data through WordPress websites. Unauthorized access to form submissions can lead to exposure of personal data, violating GDPR and other privacy regulations, potentially resulting in legal penalties and reputational damage. Organizations in sectors such as healthcare, finance, education, and e-commerce, where sensitive data is frequently collected, are particularly vulnerable. The breach of confidentiality could also facilitate social engineering, phishing, or identity theft attacks. Since the vulnerability can be exploited without authentication or user interaction, attackers can automate exploitation attempts, increasing the risk of widespread data compromise. Additionally, the exposure of form data could undermine trust in the affected organizations and their websites. The absence of known exploits currently provides a window for mitigation, but the risk remains high due to the ease of exploitation and the sensitive nature of the data involved.

To mitigate CVE-2025-14072, organizations should immediately update the Ninja Forms plugin to version 3.13.3 or later, where the vulnerability is addressed. Until the update is applied, administrators should restrict access to the WordPress REST API endpoints related to Ninja Forms by implementing IP whitelisting or authentication requirements at the web server or application firewall level. Monitoring web server logs for unusual REST API token generation requests can help detect exploitation attempts. Additionally, organizations should review and audit form submission data access permissions and consider encrypting stored form data to reduce the impact of potential data leaks. Regular backups and incident response plans should be updated to include scenarios involving unauthorized data access via plugins. Finally, educating site administrators about the risks of outdated plugins and enforcing strict update policies can prevent similar vulnerabilities from persisting.
