CVE-2025-66079 identifies a missing authorization vulnerability in the Jegstudio Gutenverse Form plugin, a WordPress form management tool widely used for creating and managing forms on websites. The vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict user permissions. This misconfiguration allows attackers to bypass authorization checks, potentially enabling them to perform actions reserved for privileged users without proper authentication or permission. The affected versions include all releases up to and including version 2.2.0, with no specific version range provided beyond that. The vulnerability does not currently have a CVSS score, and no public exploits have been reported. However, the nature of missing authorization issues typically allows attackers to manipulate form data, access sensitive information, or alter form configurations, impacting the confidentiality and integrity of the affected systems. Since Gutenverse Form is a plugin for WordPress, the vulnerability's reach depends on the plugin's deployment across websites, which can be extensive given WordPress's popularity. The issue was published on November 21, 2025, by Patchstack, indicating it is a recent discovery requiring attention from site administrators and security teams. No patches or fixes are linked yet, suggesting that mitigation may currently rely on configuration changes or temporary workarounds until an official update is released.

For European organizations, the missing authorization vulnerability in Gutenverse Form poses significant risks, especially for entities relying on WordPress-based websites for customer interaction, data collection, or internal workflows. Exploitation could lead to unauthorized access to form submissions, manipulation of form data, or unauthorized changes to form settings, potentially resulting in data breaches, loss of data integrity, or disruption of business processes. Organizations handling sensitive personal data, such as those in finance, healthcare, or e-commerce sectors, face heightened risks of regulatory non-compliance under GDPR if unauthorized data access occurs. Additionally, attackers could leverage this vulnerability to conduct further attacks, such as injecting malicious content or pivoting within the network if the compromised site is part of a larger infrastructure. The absence of authentication requirements for exploitation increases the threat level, making it easier for remote attackers to abuse the vulnerability without needing valid credentials. This could lead to widespread impact across multiple organizations using the plugin, especially if automated exploit tools emerge. The lack of known exploits currently provides a window for proactive defense, but the risk remains substantial given the potential consequences.

European organizations should immediately audit their WordPress installations to identify the presence of the Gutenverse Form plugin and determine the version in use. Until an official patch is released, administrators should restrict access to form management interfaces by implementing strict role-based access controls and limiting administrative privileges to trusted personnel only. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting form endpoints. Monitoring and logging access to form-related functions should be enhanced to detect anomalous activities indicative of exploitation attempts. Organizations should also consider temporarily disabling the Gutenverse Form plugin if it is not critical to operations or replacing it with alternative, secure form plugins. Regularly check for updates from Jegstudio and apply patches promptly once available. Additionally, conduct security awareness training for site administrators to recognize and respond to potential exploitation signs. Finally, implement network segmentation to limit the impact of any successful compromise and ensure backups of website data are maintained to enable recovery.
