CVE-2026-2002 is a stored Cross-Site Scripting (XSS) vulnerability identified in the Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress, affecting all versions up to and including 1.50.2. The vulnerability stems from improper neutralization of input during web page generation, specifically inadequate sanitization and escaping of the form_name parameter. This flaw allows authenticated attackers, typically with administrator-level privileges or delegated form management permissions, to inject arbitrary JavaScript code into form-related pages. When other users access these pages, the injected scripts execute in their browsers, potentially leading to session hijacking, credential theft, or unauthorized actions within the context of the victim's session. The plugin’s feature that permits administrators to delegate form management to lower-privileged users (such as subscribers) broadens the attack surface, enabling less privileged users to exploit the vulnerability if such permissions are granted. The CVSS v3.1 base score is 4.4, reflecting a medium severity with network attack vector, high attack complexity, and requiring privileges but no user interaction. The vulnerability impacts confidentiality and integrity but not availability. No public exploits have been reported yet, and no official patches are linked in the provided data, indicating that mitigation may currently rely on configuration changes or access control adjustments. This vulnerability is particularly relevant for websites relying on Forminator Forms for contact, payment, or custom forms, which are common in WordPress-powered sites globally.

For European organizations, the impact of CVE-2026-2002 can be significant, especially for those relying on WordPress sites with the Forminator Forms plugin for customer interaction, payment processing, or data collection. Successful exploitation could lead to unauthorized script execution in users’ browsers, resulting in theft of sensitive information such as session cookies, personal data, or payment details. This can undermine customer trust, lead to data breaches under GDPR regulations, and cause reputational damage. The ability for lower-privileged users to exploit the vulnerability if granted form management permissions increases insider threat risks. Although the vulnerability does not affect availability, the compromise of confidentiality and integrity can have legal and financial consequences. Organizations in sectors like e-commerce, finance, healthcare, and public services, which often use WordPress for their web presence, are particularly at risk. The medium severity score suggests that while exploitation is not trivial, the potential damage warrants prompt attention.

To mitigate CVE-2026-2002, European organizations should first verify if they use the Forminator Forms plugin and identify the version in use. Immediate steps include restricting form management permissions strictly to trusted administrators and avoiding delegation to lower-privileged users until a patch is available. Implementing Web Application Firewall (WAF) rules to detect and block suspicious input patterns targeting the form_name parameter can reduce exploitation risk. Monitoring logs for unusual form submissions or script injections is advised. Organizations should follow wpmudev’s updates closely and apply security patches as soon as they are released. Additionally, employing Content Security Policy (CSP) headers can help mitigate the impact of injected scripts by restricting script execution sources. Regular security audits and user privilege reviews will help minimize exposure. If patching is delayed, consider temporarily disabling the plugin or replacing it with alternative form solutions that do not have this vulnerability.
