CVE-2024-13783 in FormCraft Plugin
Summary
by MITRE • 02/18/2025
The FormCraft plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check in formcraft-main.php in all versions up to, and including, 3.9.11. This makes it possible for authenticated attackers, with Subscriber-level access and above, to export all plugin data which may contain sensitive information from form submissions.

The vulnerability identified as CVE-2024-13783 resides within the FormCraft plugin for WordPress, a widely used tool for creating and managing online forms. This security flaw represents a critical access control weakness that undermines the integrity of user data protection mechanisms. The vulnerability stems from a missing capability check within the formcraft-main.php file, which is present in all versions up to and including 3.9.11. This omission creates a significant security gap that allows authenticated attackers to exploit the system without proper authorization. The flaw specifically affects users who possess Subscriber-level access or higher privileges within the WordPress environment, making it particularly concerning given the commonality of such user roles in many WordPress installations.
The technical implementation of this vulnerability occurs through the absence of proper capability verification in the data export functionality. When authenticated users with Subscriber-level permissions attempt to access the plugin's data export features, the system fails to validate whether these users possess the appropriate administrative privileges required to access sensitive form submission data. This missing validation creates an unauthorized access vector that bypasses the intended permission model of WordPress. The vulnerability falls under CWE-284, which specifically addresses improper access control, and aligns with ATT&CK technique T1078 for valid accounts and T1566 for credential harvesting. The flaw essentially allows attackers to escalate their privileges through data exfiltration rather than direct code execution or other more complex attack vectors.
The operational impact of this vulnerability extends beyond simple data exposure, as it can lead to significant privacy violations and potential regulatory compliance issues. FormCraft plugins typically collect sensitive information from users including personal details, contact information, and other confidential data submitted through various forms. When attackers can export all plugin data without proper authorization, they gain access to potentially thousands of records containing personally identifiable information, business data, or other sensitive material. This exposure creates risks for organizations that may face legal consequences under data protection regulations such as GDPR, CCPA, or other applicable privacy laws. The vulnerability also poses risks to user trust and brand reputation, as unauthorized access to form submissions can expose confidential communications or personal information that users reasonably expect to remain secure.
Mitigation strategies for CVE-2024-13783 should focus on immediate remediation through plugin updates to versions that address the missing capability check. WordPress administrators should prioritize updating the FormCraft plugin to the latest available version that contains the necessary security patches. Organizations should also implement additional monitoring measures to detect unauthorized access attempts to form data export functions, particularly for users with lower privilege levels. Network segmentation and access control measures can help limit the impact of potential exploitation by restricting access to sensitive plugin features. Security teams should conduct thorough audits of all installed plugins to identify similar capability check vulnerabilities and ensure proper access controls are implemented across the entire WordPress ecosystem. The ATT&CK framework suggests implementing defensive measures such as access control monitoring and user behavior analysis to detect anomalous access patterns that might indicate exploitation attempts. Regular security assessments and penetration testing should be conducted to identify and remediate similar vulnerabilities before they can be exploited by malicious actors.
