CVE-2025-6207 is a high-severity vulnerability affecting the WP Import Export Lite plugin for WordPress, developed by vjinfotech. The vulnerability arises from the lack of proper file type validation in the 'wpie_tempalte_import' function across all plugin versions up to and including 3.9.28. This flaw allows authenticated attackers with Subscriber-level access or higher, granted permissions by an Administrator, to upload arbitrary files to the affected WordPress site's server. Because the plugin does not restrict or validate the file types being uploaded, attackers can potentially upload malicious files such as web shells or scripts that could lead to remote code execution (RCE). The vulnerability is classified under CWE-434, which pertains to unrestricted file upload vulnerabilities that can lead to execution of malicious code or other attacks. The CVSS v3.1 base score is 7.5, indicating a high severity, with the vector string CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H. This means the attack can be performed remotely over the network, requires low privileges (authenticated Subscriber-level user), no user interaction, and can impact confidentiality, integrity, and availability significantly. Although no known exploits are currently reported in the wild, the potential for exploitation is considerable due to the widespread use of WordPress and the plugin's functionality. The vulnerability requires that an attacker have at least Subscriber-level access and permissions granted by an Administrator, which implies some level of internal compromise or social engineering to gain initial access. Once exploited, attackers can upload malicious files that may enable full system compromise, data theft, defacement, or further lateral movement within the hosting environment.

For European organizations, this vulnerability poses a significant risk, especially for those relying on WordPress websites for business operations, e-commerce, or public-facing services. Successful exploitation could lead to unauthorized access to sensitive data, defacement of websites, disruption of services, and potential data breaches that would invoke GDPR reporting requirements and penalties. The ability to execute arbitrary code remotely could allow attackers to pivot into internal networks, escalate privileges, or deploy ransomware. Organizations in sectors such as finance, healthcare, government, and e-commerce are particularly at risk due to the sensitivity of their data and the critical nature of their web services. The requirement for authenticated access reduces the attack surface somewhat but does not eliminate risk, as attackers often obtain low-level credentials through phishing or other means. Additionally, compromised WordPress sites can be used as launchpads for further attacks or to distribute malware, impacting the broader European digital ecosystem.

To mitigate this vulnerability, European organizations should immediately update the WP Import Export Lite plugin to a patched version once available. Until a patch is released, organizations should restrict plugin usage to trusted administrators only and review user roles to minimize the number of users with upload permissions. Implement strict access controls and monitor user activities for suspicious file uploads. Employ web application firewalls (WAFs) with rules to detect and block malicious file uploads and anomalous HTTP requests targeting the vulnerable function. Conduct regular security audits and vulnerability scans on WordPress installations and plugins. Additionally, disable or restrict file upload capabilities in the plugin if not essential. Organizations should also enforce multi-factor authentication (MFA) to reduce the risk of credential compromise and ensure timely backups of website data to enable recovery in case of compromise. Monitoring server logs for unusual file creation or execution attempts can provide early detection of exploitation attempts.
