CVE-2025-11363 is a vulnerability classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) found in the Royal Addons for Elementor WordPress plugin, versions prior to 1.7.1037. The flaw arises because the plugin fails to enforce proper authorization checks on the wpr_addons_upload_file action, allowing unauthenticated users to upload arbitrary media files. This lack of access control means that any attacker can upload files without logging in or interacting with the system beyond sending a crafted request. The vulnerability does not impact confidentiality directly but compromises integrity by enabling the upload of potentially malicious files, such as web shells or scripts, which can be used to execute arbitrary code or conduct further attacks on the hosting server. The CVSS v3.1 score is 5.3 (medium), reflecting the network attack vector, no required privileges, no user interaction, and limited impact on integrity without affecting confidentiality or availability. No known public exploits have been reported yet, but the vulnerability's nature makes it a candidate for exploitation once weaponized. The plugin is widely used in WordPress environments, which are prevalent globally, including Europe. The absence of a patch link indicates that a fix may not yet be publicly available, emphasizing the need for vigilance and interim protective measures.

For European organizations, this vulnerability poses a moderate risk primarily to websites using the Royal Addons for Elementor plugin. Successful exploitation could allow attackers to upload malicious files, leading to website defacement, malware distribution, or pivoting to deeper network compromise. This can damage organizational reputation, cause service disruptions, and potentially lead to data integrity issues if attackers modify or replace legitimate content. Since WordPress powers a significant portion of European websites, especially in sectors like e-commerce, media, and public services, the impact could be widespread. Organizations with less mature patch management or security monitoring are particularly vulnerable. Additionally, regulatory frameworks such as GDPR impose strict requirements on data integrity and security, so exploitation could result in compliance violations and penalties. The medium severity score suggests that while the threat is not critical, it should not be ignored, especially given the ease of exploitation and the potential for chained attacks.

1. Monitor official Royal Addons for Elementor channels for the release of version 1.7.1037 or later that addresses this vulnerability and apply the update immediately upon availability. 2. Until a patch is available, implement web application firewall (WAF) rules to block or restrict access to the wpr_addons_upload_file endpoint, limiting file upload attempts from unauthenticated sources. 3. Enforce strict file type validation and scanning on all uploaded files to detect and quarantine potentially dangerous content. 4. Restrict file permissions on the server to prevent execution of uploaded files in upload directories. 5. Conduct regular security audits and monitoring of web server logs to detect anomalous upload activity. 6. Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts targeting this vulnerability. 7. Educate site administrators about the risks of using outdated plugins and the importance of timely updates. 8. Consider temporarily disabling the Royal Addons for Elementor plugin if it is not critical to operations until a patch is available.
