CVE-2025-62065 is a critical security vulnerability identified in the Rometheme RTMKit plugin for Elementor, a popular WordPress page builder extension. The vulnerability is characterized as an 'Unrestricted Upload of File with Dangerous Type,' meaning the plugin fails to properly restrict the types of files that can be uploaded by users with low privileges. This flaw exists in all versions up to and including 1.6.5. An attacker with low-level privileges (PR:L) can remotely upload malicious files without requiring any user interaction (UI:N), exploiting the vulnerability over the network (AV:N). The vulnerability has a CVSS v3.1 base score of 9.9, indicating critical severity with complete impact on confidentiality, integrity, and availability (C:H/I:H/A:H). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The unrestricted file upload can lead to remote code execution, enabling attackers to execute arbitrary code on the server, potentially leading to full system compromise. The vulnerability is particularly dangerous because it does not require user interaction and can be exploited remotely with low privileges, increasing the attack surface. No patches or exploit code are currently publicly available, but the risk remains high due to the nature of the vulnerability and the widespread use of RTMKit in WordPress environments.

For European organizations, this vulnerability poses a significant threat to websites and web applications using the RTMKit plugin. Successful exploitation can lead to unauthorized access, data theft, defacement, or complete server takeover, impacting confidentiality, integrity, and availability of critical systems. Organizations in sectors such as e-commerce, government, healthcare, and finance that rely on WordPress-based platforms are particularly vulnerable. The critical severity and ease of exploitation mean attackers can quickly compromise systems remotely, potentially leading to data breaches, service disruptions, and reputational damage. Given the interconnected nature of European digital infrastructure, a successful attack could also serve as a pivot point for lateral movement within networks. Compliance with GDPR and other data protection regulations could be jeopardized if personal data is exposed due to this vulnerability.

Immediate mitigation steps include monitoring for updates from Rometheme and applying patches as soon as they become available. Until patches are released, organizations should implement strict file upload restrictions at the web server or application firewall level, blocking dangerous file types such as executable scripts (.php, .exe, .js). Employing a Web Application Firewall (WAF) with custom rules to detect and block suspicious upload attempts can reduce risk. Restricting user privileges to the minimum necessary and auditing user accounts with upload capabilities can limit exposure. Additionally, organizations should conduct regular security assessments and penetration tests focusing on file upload functionalities. Implementing robust logging and monitoring to detect anomalous file uploads or execution attempts is critical. Backup strategies should be reviewed and tested to ensure rapid recovery in case of compromise. Finally, educating administrators and developers about secure file handling practices will help prevent similar issues.
