CVE-2024-51651 identifies a Missing Authorization vulnerability in the CubeWP Forms plugin for WordPress, developed by Imran Tauqeer. The vulnerability exists due to incorrectly configured access control security levels, which fail to properly restrict unauthorized users from accessing or manipulating form-related functionalities. This can allow attackers to perform actions that should be limited to authenticated or privileged users, potentially leading to unauthorized data access, modification, or disruption of form operations. The affected versions include all releases up to and including 1.1.10. The vulnerability was reserved on October 30, 2024, and published on January 7, 2025. No CVSS score has been assigned yet, and no known exploits have been reported in the wild. CubeWP Forms is a WordPress plugin used to create and manage forms on websites, and improper authorization can compromise the integrity and confidentiality of form data and site operations. The issue stems from a failure to enforce proper authorization checks before granting access to sensitive plugin functions, which is a common security oversight in web applications. This vulnerability highlights the importance of robust access control mechanisms in WordPress plugins, especially those handling user input and data collection.

The potential impact of CVE-2024-51651 includes unauthorized access to form management features, which could lead to data leakage, unauthorized data modification, or disruption of form services on affected websites. Attackers exploiting this vulnerability might gain the ability to manipulate form submissions, access sensitive user data collected via forms, or interfere with website functionality. For organizations, this could result in compromised customer data, loss of trust, regulatory compliance issues, and potential reputational damage. Since CubeWP Forms is a WordPress plugin, the scope of impact depends on the prevalence of this plugin among WordPress sites, which are widely used globally. The vulnerability could be leveraged as a foothold for further attacks within the compromised site environment, including privilege escalation or lateral movement. Although no exploits are currently known, the ease of exploitation is potentially high given the nature of missing authorization flaws, which often require no user interaction or complex conditions. The impact is primarily on confidentiality and integrity, with possible availability implications if form functionality is disrupted.

To mitigate CVE-2024-51651, organizations should immediately audit access control configurations for CubeWP Forms and restrict access to form management interfaces to trusted, authenticated users only. Administrators should monitor logs for unusual activity related to form operations and implement web application firewall (WAF) rules to detect and block unauthorized access attempts. Until an official patch is released, consider disabling the plugin if it is not critical or replacing it with alternative form plugins that have verified secure authorization controls. Regularly update WordPress core and plugins to the latest versions to benefit from security fixes. Developers maintaining CubeWP Forms should implement strict authorization checks on all sensitive operations and conduct thorough security testing to prevent similar issues. Additionally, organizations should educate site administrators on the risks of improper access control and encourage the use of least privilege principles for user roles.
