CVE-2025-62094 identifies a Cross-site Scripting (XSS) vulnerability classified under CWE-79 in the Voidthemes Void Elementor WHMCS Elements plugin for Elementor Page Builder, affecting versions up to 2.0.1.2. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows an attacker to inject malicious scripts into pages rendered by the plugin. This can occur when the plugin fails to adequately sanitize or encode input fields that are reflected in the HTML output, enabling script execution in the context of the victim's browser. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) indicates that the attack can be launched remotely over the network with low attack complexity, requires low privileges (authenticated user), and user interaction (such as clicking a crafted link) is necessary. The vulnerability affects the confidentiality, integrity, and availability of the affected web application, potentially allowing attackers to steal session cookies, manipulate page content, or disrupt service availability. Although no public exploits have been reported yet, the presence of this vulnerability in a popular WordPress plugin used for integrating WHMCS elements into Elementor-built sites poses a tangible risk. The vulnerability's scope is considered changed (S:C), meaning the impact can extend beyond the vulnerable component to other parts of the system or users. The plugin is commonly used by hosting providers and web agencies to integrate billing and client management features, making the affected installations attractive targets for attackers aiming to compromise customer data or disrupt services.

For European organizations, especially those operating web hosting, SaaS, or e-commerce platforms using WordPress with the Void Elementor WHMCS Elements plugin, this vulnerability could lead to unauthorized access to user sessions, theft of sensitive client information, and potential defacement or disruption of services. The compromise of client billing or management portals could damage reputation and lead to regulatory non-compliance under GDPR due to exposure of personal data. Since the vulnerability requires authenticated access and user interaction, insider threats or social engineering attacks could facilitate exploitation. The partial compromise of confidentiality, integrity, and availability could also enable attackers to pivot to further attacks within the network. Given the widespread use of WordPress and Elementor in Europe, the risk is non-trivial, particularly for SMEs and hosting providers who rely on this plugin for client management integration.

Organizations should monitor Voidthemes’ official channels for patches and apply updates to the Void Elementor WHMCS Elements plugin as soon as they become available. In the interim, implement strict input validation and output encoding on all user-supplied data fields rendered by the plugin to prevent script injection. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. Limit plugin access to trusted authenticated users and enforce multi-factor authentication to reduce the risk of credential compromise. Conduct regular security audits and penetration testing focusing on web application input handling. Additionally, educate users about phishing and social engineering risks to minimize successful exploitation requiring user interaction. Consider isolating critical client management interfaces behind VPNs or additional access controls to reduce exposure.
