CVE-2024-56002 identifies a missing authorization vulnerability in the MightyForms Contact Form, Survey & Form Builder plugin, specifically affecting versions up to and including 1.3.9. The vulnerability arises from incorrectly configured access control security levels, which fail to properly enforce authorization checks on certain functionalities within the plugin. This misconfiguration allows an attacker to bypass intended access restrictions, potentially performing unauthorized actions such as modifying form configurations, accessing submitted data, or manipulating survey results. The plugin is commonly used in WordPress environments to create and manage contact forms, surveys, and other data collection tools, making it a critical component in many websites’ user interaction workflows. Although no public exploits have been reported yet, the flaw’s nature suggests that exploitation could be straightforward if an attacker can interact with the vulnerable endpoints, especially if authentication is weak or absent. The vulnerability impacts the confidentiality and integrity of data processed by the plugin and could also affect availability if exploited to disrupt normal form operations. No official CVSS score has been assigned, but based on the missing authorization classification, the risk is significant. The vulnerability was reserved in mid-December 2024 and published at the end of the year, indicating recent discovery and disclosure. No patches or fixes are currently linked, so users must monitor vendor communications closely. This vulnerability underscores the importance of rigorous access control validation in web application plugins, particularly those handling user-generated content and sensitive data.

The potential impact of CVE-2024-56002 is substantial for organizations relying on the MightyForms plugin for customer engagement, data collection, and survey management. Exploitation could lead to unauthorized access to sensitive form data, including personally identifiable information (PII) or business-critical inputs, compromising confidentiality. Attackers might alter form configurations or survey results, undermining data integrity and trustworthiness. In some scenarios, attackers could disrupt form availability, causing denial of service to legitimate users. Such impacts can damage organizational reputation, lead to regulatory non-compliance (e.g., GDPR, CCPA), and result in financial losses due to data breaches or operational downtime. Since the plugin is integrated into websites, exploitation could also serve as a foothold for further attacks within the hosting environment. The absence of known exploits currently limits immediate widespread damage, but the vulnerability’s nature makes it a prime target once weaponized. Organizations with high volumes of user interactions or sensitive data processed through MightyForms are particularly at risk. The impact extends across sectors including e-commerce, healthcare, education, and government services that utilize web forms for critical workflows.

To mitigate CVE-2024-56002 effectively, organizations should take several specific steps beyond generic advice: 1) Immediately audit and restrict access permissions to the MightyForms plugin, ensuring only trusted administrators have modification rights. 2) Implement web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting form management endpoints. 3) Monitor logs for unusual activity patterns such as unauthorized API calls or configuration changes within the plugin. 4) Temporarily disable or limit the plugin’s functionality if possible until an official patch is released. 5) Engage with the MightyForms vendor or community to obtain early patches or workarounds addressing the missing authorization issue. 6) Conduct penetration testing focused on access control validation for the plugin to identify any additional weaknesses. 7) Educate site administrators about the risks of improper access control and best practices for managing plugin permissions. 8) Maintain up-to-date backups of form data and configurations to enable rapid recovery if exploitation occurs. 9) Consider isolating the plugin’s functionality within a segmented environment to reduce lateral movement risks. These targeted actions will reduce the attack surface and improve resilience against exploitation of this vulnerability.
