CVE-2025-11363 is a security vulnerability classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) affecting the Royal Addons for Elementor WordPress plugin prior to version 1.7.1037. The vulnerability arises due to insufficient authorization checks on the wpr_addons_upload_file action, which allows unauthenticated users to upload media files without restriction. This means an attacker can upload arbitrary files, including potentially malicious scripts or web shells, directly to the server hosting the WordPress site. Such files could be used to execute remote code, deface websites, steal sensitive data, or pivot to further internal network compromise. The vulnerability does not require any authentication or user interaction, making it highly exploitable, especially by automated bots scanning for vulnerable WordPress instances. Although no public exploits are currently known, the nature of the vulnerability and the popularity of the affected plugin increase the likelihood of future exploitation. The absence of a CVSS score requires an assessment based on impact and exploitability factors. The vulnerability impacts confidentiality, integrity, and availability by enabling unauthorized file uploads that can lead to remote code execution or data breaches. The scope is broad, as any site running the affected plugin version is vulnerable. The plugin is widely used in WordPress environments, which are prevalent across many European organizations for web content management and e-commerce. The vulnerability's publication date is December 15, 2025, with the issue reserved in early October 2025, indicating recent discovery and disclosure. No patch links are currently available, emphasizing the need for vigilance and interim mitigations.

For European organizations, this vulnerability poses a significant risk to website security and data integrity. Organizations relying on WordPress with the Royal Addons for Elementor plugin could face unauthorized website defacement, data leakage, or complete server compromise if attackers upload and execute malicious files. This can lead to reputational damage, loss of customer trust, regulatory penalties under GDPR if personal data is exposed, and operational disruptions. Automated exploitation attempts could increase, targeting vulnerable sites across Europe. The impact is especially critical for sectors with high web exposure such as e-commerce, media, and public institutions. Additionally, compromised websites could be used as launchpads for further attacks within corporate networks or for distributing malware to visitors. The lack of authentication requirement lowers the barrier for attackers, increasing the urgency for mitigation. Organizations without timely patching or compensating controls risk severe consequences including data breaches and service outages.

1. Immediately monitor for any suspicious file upload activity related to the wpr_addons_upload_file action in web server logs and WordPress logs. 2. Implement web application firewall (WAF) rules to block unauthorized POST requests to the upload endpoint or restrict upload file types to safe extensions. 3. Disable or restrict the Royal Addons for Elementor plugin if patching is not yet available, especially on public-facing sites. 4. Enforce strict file upload validation and sanitization policies at the application and server level, including MIME type checks and file content inspection. 5. Regularly audit installed WordPress plugins and update them promptly once a patch for this vulnerability is released. 6. Employ intrusion detection systems (IDS) to detect anomalous upload behavior or web shell signatures. 7. Limit permissions on upload directories to prevent execution of uploaded files. 8. Educate site administrators about this vulnerability and encourage immediate action to reduce exposure. 9. Consider isolating WordPress instances in segmented network zones to limit lateral movement if compromise occurs.
