CVE-2025-13094 is a vulnerability classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) found in the WP3D Model Import Viewer plugin for WordPress. The vulnerability arises from the handle_import_file() function, which lacks proper validation of uploaded file types. This flaw allows authenticated users with Author-level privileges or higher to upload arbitrary files to the web server hosting the WordPress site. Since the plugin does not restrict file types, attackers can upload malicious scripts or executables, potentially leading to remote code execution (RCE). The vulnerability affects all versions up to and including 1.0.7. The CVSS v3.1 score of 8.8 reflects the ease of exploitation (network attack vector, low attack complexity, privileges required but no user interaction) and the severe impact on confidentiality, integrity, and availability of the affected systems. Although no exploits are publicly known yet, the vulnerability poses a significant risk because WordPress is widely used, and plugins often have elevated privileges on the server. Attackers gaining Author-level access can leverage this vulnerability to escalate privileges, implant backdoors, or disrupt services. The lack of patch links suggests a fix is pending or not yet publicly released, emphasizing the need for immediate mitigation steps.

For European organizations, this vulnerability poses a critical risk, especially for those relying on WordPress for business-critical websites, e-commerce platforms, or content management. Successful exploitation can lead to full server compromise, data breaches, defacement, or service outages. Confidential information stored or processed by the website could be exposed or altered, damaging organizational reputation and compliance with GDPR and other data protection regulations. The ability to execute arbitrary code remotely increases the risk of lateral movement within internal networks, potentially affecting other systems. Organizations with multiple WordPress instances or those allowing Author-level user roles broadly are particularly vulnerable. The threat is amplified in sectors such as finance, healthcare, media, and government, where website integrity and data confidentiality are paramount. Additionally, the absence of public exploits currently provides a window for proactive defense, but this may close rapidly once exploit code becomes available.

1. Immediately audit WordPress sites for the presence of the WP3D Model Import Viewer plugin and identify versions up to 1.0.7. 2. Restrict or remove Author-level user privileges where possible, limiting upload capabilities to trusted users only. 3. Implement strict file upload controls at the web server or application firewall level to block dangerous file types and extensions commonly used for code execution (e.g., .php, .exe, .js). 4. Monitor file upload directories for unexpected or suspicious files and implement integrity checks. 5. Employ web application firewalls (WAFs) with rules targeting arbitrary file upload attempts. 6. Keep WordPress core, themes, and plugins updated; apply security patches promptly once the vendor releases a fix for this vulnerability. 7. Conduct regular security audits and penetration tests focusing on plugin vulnerabilities and user privilege misuse. 8. Educate site administrators and content creators on the risks of elevated privileges and safe upload practices. 9. Consider isolating WordPress instances in segmented network zones to limit potential lateral movement. 10. Prepare incident response plans to quickly address any signs of compromise related to this vulnerability.
