CVE-2025-64355 is a DOM-based Cross-site Scripting (XSS) vulnerability classified under CWE-79, found in the Crocoblock JetElements plugin for Elementor, a popular WordPress page builder add-on. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows malicious scripts to be injected and executed within the victim's browser context. This flaw affects all versions up to 2.7.12. The attack vector requires network access (remote), low attack complexity, and low privileges, but does require user interaction (e.g., clicking a crafted link or visiting a malicious page). The vulnerability has a CVSS 3.1 base score of 6.5, indicating medium severity, with impacts on confidentiality, integrity, and availability. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component, potentially impacting the entire web application. No known exploits have been reported in the wild, and no official patches have been published yet. The vulnerability allows attackers to execute arbitrary JavaScript code in the context of users visiting affected websites, potentially leading to session hijacking, data theft, defacement, or further exploitation. The plugin is widely used in WordPress environments, especially for e-commerce and content-rich sites, making it a significant risk vector.

For European organizations, this vulnerability poses a risk to the confidentiality of user data, including personal and financial information, due to potential session hijacking and data theft. Integrity of website content and user interactions can be compromised, leading to misinformation or unauthorized actions performed on behalf of users. Availability may also be affected if attackers leverage the vulnerability to deface websites or disrupt services. Organizations in sectors such as e-commerce, finance, and media, which rely heavily on WordPress and Elementor with JetElements, are particularly vulnerable. The vulnerability can erode customer trust and lead to regulatory penalties under GDPR if personal data is compromised. Given the widespread use of WordPress in Europe, the threat surface is substantial, especially for small and medium enterprises that may lack robust security controls.

1. Immediately audit all WordPress sites using JetElements for Elementor to identify affected versions (up to 2.7.12). 2. Apply strict input validation and sanitization on all user-supplied data, especially in custom code or additional plugins interacting with JetElements. 3. Implement a strong Content Security Policy (CSP) to restrict execution of unauthorized scripts and reduce XSS impact. 4. Monitor web server and application logs for unusual requests or script injection attempts targeting JetElements components. 5. Educate users and administrators about the risks of clicking unknown links or visiting untrusted pages to reduce successful exploitation via user interaction. 6. Once an official patch or update is released by Crocoblock, prioritize immediate deployment across all affected environments. 7. Consider deploying Web Application Firewalls (WAFs) with rules targeting XSS payloads specific to JetElements. 8. Regularly backup website data and configurations to enable quick recovery in case of compromise.
