CVE-2025-9978 is a cross-site scripting (XSS) vulnerability classified under CWE-79 found in the Jeg Kit for Elementor WordPress plugin before version 2.7.0. The vulnerability stems from improper sanitization of SVG file contents uploaded through the xmlrpc.php endpoint, a WordPress interface that allows remote procedure calls including file uploads. SVG files are XML-based vector images that can contain embedded scripts. Because the plugin does not sanitize these SVG contents, an attacker can craft malicious SVG files containing JavaScript payloads. When such a file is uploaded and later rendered in a victim's browser, the embedded script executes in the context of the site, potentially leading to session hijacking, defacement, or further malware delivery. The vulnerability does not require authentication to exploit if xmlrpc.php is enabled and accessible, which is common in many WordPress installations. Although no known exploits are currently reported in the wild, the public disclosure and the nature of the vulnerability make it a significant risk. The lack of a CVSS score means severity must be inferred from impact and exploitability. The vulnerability affects all versions of Jeg Kit for Elementor prior to 2.7.0, and no official patch links are currently provided, indicating that users should monitor for updates or apply manual mitigations. The xmlrpc.php interface is often targeted because it is enabled by default and can be abused for various attacks, including brute force and file upload exploits. This vulnerability adds another risk vector by allowing malicious SVG uploads that bypass sanitization. Organizations using this plugin on WordPress sites should prioritize mitigation to prevent client-side code execution attacks.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of web applications using the Jeg Kit for Elementor plugin. Successful exploitation can lead to session hijacking, unauthorized actions performed on behalf of users, defacement of websites, and potential malware distribution. This can damage organizational reputation, lead to data breaches involving user information, and disrupt business operations. Given the widespread use of WordPress across Europe, especially among small and medium enterprises and public sector websites, the attack surface is considerable. The vulnerability is particularly impactful for organizations that rely on xmlrpc.php for remote management or have it enabled without restrictions. Additionally, the ability to upload malicious SVG files could bypass traditional file upload filters, increasing the risk of persistent XSS attacks. The absence of known exploits in the wild provides a window for proactive defense, but the public disclosure increases the likelihood of attackers developing exploits. Regulatory frameworks such as GDPR impose strict data protection requirements, and exploitation leading to data breaches could result in significant fines and legal consequences for European entities.

European organizations should immediately audit their WordPress installations to identify the use of the Jeg Kit for Elementor plugin and verify the version in use. Until an official patch (version 2.7.0 or later) is released and applied, organizations should consider disabling or restricting access to xmlrpc.php, especially from untrusted networks, using web application firewalls (WAFs) or server-level access controls. Implement strict file upload validation and filtering to block SVG files or sanitize SVG content using specialized libraries that remove scripts and potentially dangerous elements. Monitoring web server logs for unusual xmlrpc.php activity can help detect exploitation attempts. Employ Content Security Policy (CSP) headers to limit the impact of any injected scripts. Regularly update all WordPress plugins and core installations to reduce exposure to known vulnerabilities. Educate site administrators about the risks of enabling xmlrpc.php and encourage the use of alternative secure management methods. Finally, prepare incident response plans to quickly address any detected exploitation attempts.
