CVE-2024-54218 identifies a Missing Authorization vulnerability in thehp AIO Contact plugin, a WordPress plugin used for managing contact forms and related data. The vulnerability affects all versions up to and including 2.8.1. Missing Authorization means that certain functionality or endpoints within the plugin do not properly verify whether the user has the necessary permissions before allowing access or actions. This can lead to unauthorized users, including unauthenticated attackers, performing actions or accessing data that should be restricted. The lack of a CVSS score indicates that the vulnerability is newly disclosed and has not yet been fully evaluated for severity. No known exploits have been reported in the wild, but the potential for abuse exists given the nature of the flaw. The vulnerability impacts the confidentiality and integrity of data handled by the plugin, such as contact form submissions or administrative settings. Since thehp AIO Contact is a WordPress plugin, it is typically deployed on websites running WordPress, which is a widely used content management system globally. The vulnerability could be exploited remotely without authentication, increasing the risk profile. The absence of patches at the time of disclosure means organizations must rely on interim mitigations until official updates are released. The vulnerability was reserved on December 2, 2024, and published on December 9, 2024, indicating a recent disclosure. The vulnerability is assigned by Patchstack, a known security authority for WordPress plugins.

The Missing Authorization vulnerability in thehp AIO Contact plugin can have significant impacts on organizations worldwide. Unauthorized access to contact form data could lead to exposure of sensitive personal or business information, violating privacy regulations such as GDPR or CCPA. Attackers could manipulate contact data or plugin settings, potentially disrupting communication channels or injecting malicious content. The integrity of the website’s contact functionality could be compromised, undermining trust with users and customers. Since WordPress powers a large portion of the web, any website using this plugin is at risk, potentially affecting small businesses, enterprises, and government sites alike. The ease of exploitation without authentication increases the likelihood of attacks, especially if automated scanning tools identify vulnerable sites. This could lead to data breaches, reputational damage, and compliance penalties. Additionally, attackers might leverage this vulnerability as a foothold for further attacks within the compromised environment. The lack of current known exploits provides a limited window for organizations to prepare and respond before active exploitation emerges.

Organizations using thehp AIO Contact plugin should immediately audit their WordPress installations to identify affected versions (up to 2.8.1). Until an official patch is released, administrators should restrict access to the plugin’s administrative and API endpoints using web application firewalls (WAFs), IP whitelisting, or other access control mechanisms. Monitoring web server and application logs for unusual or unauthorized access attempts targeting the plugin’s functionality is critical. Implementing strict user role management and minimizing plugin usage to only trusted administrators can reduce risk. Consider temporarily disabling the plugin if feasible without disrupting critical operations. Stay informed through vendor announcements and Patchstack advisories for patch availability and apply updates promptly once released. Employing security plugins that detect and block unauthorized access attempts can provide additional protection. Conduct regular backups of website data to enable recovery in case of compromise. Finally, educate website administrators about the risks of missing authorization vulnerabilities and the importance of timely patching.
