CVE-2025-64384 identifies a missing authorization vulnerability in Jetmonsters' JetFormBuilder plugin for WordPress, affecting all versions up to and including 3.5.3. The core issue stems from improperly configured access control security levels, which fail to adequately restrict user permissions for certain operations within the plugin. This flaw allows attackers, potentially unauthenticated or with limited privileges, to perform unauthorized actions that should normally require higher privileges. Such actions could include modifying form configurations, accessing sensitive form data, or manipulating form submissions. The vulnerability does not currently have a CVSS score, nor are there known exploits in the wild, but the nature of missing authorization issues typically makes them straightforward to exploit if an attacker can interact with the vulnerable component. JetFormBuilder is widely used for creating complex forms on WordPress sites, often handling user input, registrations, and other sensitive data. Exploitation could lead to data leakage, unauthorized data modification, or disruption of form services, impacting the confidentiality, integrity, and availability of affected systems. The vulnerability was publicly disclosed on November 13, 2025, with no patch links currently available, indicating that remediation efforts are likely underway. Organizations using JetFormBuilder should urgently assess their exposure and prepare to deploy fixes once released. The vulnerability's impact is amplified in environments where JetFormBuilder is integrated into critical business workflows or customer-facing applications.

For European organizations, the missing authorization vulnerability in JetFormBuilder poses significant risks to data confidentiality and integrity, as unauthorized users could access or alter sensitive form data. This is particularly critical for sectors handling personal data under GDPR, such as finance, healthcare, and e-commerce. Unauthorized manipulation of forms could also lead to fraudulent transactions, data breaches, or service disruptions, affecting business continuity and customer trust. The availability of web forms could be compromised if attackers exploit the vulnerability to disrupt form operations, potentially impacting customer interactions and lead generation. Since JetFormBuilder is a popular WordPress plugin, organizations relying on WordPress for their web presence are at heightened risk. The absence of known exploits currently provides a window for proactive mitigation, but the ease of exploitation inherent in missing authorization flaws means that attackers could develop exploits rapidly. European entities must consider the regulatory implications of any data compromise resulting from this vulnerability, including mandatory breach notifications and potential fines.

1. Immediately audit all JetFormBuilder installations to identify affected versions (<= 3.5.3). 2. Restrict access to JetFormBuilder administrative and configuration interfaces strictly to trusted, authenticated users with a need-to-know basis. 3. Implement role-based access controls (RBAC) within WordPress to limit plugin management capabilities. 4. Monitor logs for unusual activities related to JetFormBuilder, such as unauthorized configuration changes or unexpected form submissions. 5. Stay informed on vendor advisories and apply security patches promptly once released. 6. Consider temporarily disabling JetFormBuilder on critical systems if immediate patching is not feasible. 7. Conduct penetration testing focused on access control mechanisms around JetFormBuilder to identify and remediate any additional weaknesses. 8. Educate site administrators on the risks of improper plugin permissions and the importance of timely updates. 9. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting JetFormBuilder endpoints. 10. Review and harden WordPress security configurations overall to reduce the attack surface.
