CVE-2025-6207 is a vulnerability classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) affecting the WP Import Export Lite plugin for WordPress, versions up to 3.9.28. The flaw resides in the 'wpie_tempalte_import' function, which lacks proper validation of uploaded file types. This deficiency allows authenticated attackers, even those with Subscriber-level access, to upload arbitrary files if they have permissions delegated by an Administrator. The uploaded files could include malicious scripts that enable remote code execution (RCE) on the web server hosting the WordPress site. The vulnerability is remotely exploitable over the network without requiring user interaction, but it demands low privileges and delegated permissions, which means attackers must first gain some level of authenticated access and have an administrator grant them upload permissions. The CVSS v3.1 score is 7.5 (High), reflecting the significant impact on confidentiality, integrity, and availability. Although no public exploits are currently known, the potential for exploitation is substantial given the widespread use of WordPress and this plugin. The vulnerability can lead to full site compromise, data theft, defacement, or use of the server as a pivot point for further attacks.

For European organizations, the impact of this vulnerability can be severe. Many European companies and institutions rely on WordPress for their web presence, including government agencies, educational institutions, and businesses. Exploitation could lead to unauthorized access to sensitive data, defacement of websites, disruption of services, and potential lateral movement within internal networks. Given the GDPR regulatory environment, a breach resulting from this vulnerability could also lead to significant legal and financial penalties due to data protection violations. The ability to execute arbitrary code remotely means attackers could implant backdoors, steal credentials, or launch further attacks against internal systems. Organizations with complex user role management and delegated permissions are particularly at risk, as attackers could leverage low-privilege accounts to escalate privileges and exploit the vulnerability.

To mitigate this vulnerability, European organizations should immediately audit their WordPress installations to identify the presence of the WP Import Export Lite plugin and its version. If the plugin is installed, it should be updated to a patched version as soon as it becomes available. In the absence of an official patch, organizations should consider disabling or uninstalling the plugin to eliminate the attack vector. Additionally, review and tighten user role permissions to ensure that Subscriber-level users do not have unnecessary upload permissions or delegated rights from administrators. Implement web application firewalls (WAF) with rules to detect and block suspicious file uploads targeting this plugin. Monitoring file upload directories for unauthorized or unexpected file types can help detect exploitation attempts. Regularly audit logs for unusual activity related to file uploads and user permissions. Employ the principle of least privilege for all user accounts and restrict administrative delegation. Finally, conduct security awareness training for administrators on the risks of delegating permissions to lower-privileged users.
