CVE-2025-6086 is a high-severity vulnerability affecting the CSV Me plugin for WordPress, developed by scottyla. The vulnerability arises from insufficient validation of uploaded file types in the 'csv_me_options_page' function across all versions up to and including 2.0. This flaw allows authenticated users with Administrator-level privileges or higher to upload arbitrary files to the web server hosting the affected WordPress site. Because the plugin does not properly restrict or sanitize the file types that can be uploaded, attackers can potentially upload malicious scripts or executable files. This could lead to remote code execution (RCE), enabling attackers to execute arbitrary commands on the server, compromise the website, steal sensitive data, or pivot to other internal systems. The vulnerability requires authenticated access with high privileges, meaning that exploitation is limited to users who already have administrative rights on the WordPress instance. However, given that WordPress is widely used and administrators may be targeted through phishing or credential compromise, the risk remains significant. The CVSS 3.1 base score is 7.2, reflecting high severity with network attack vector, low attack complexity, high privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. No known exploits are currently reported in the wild, but the vulnerability is publicly disclosed and could be weaponized. No patches or fixes have been published at the time of this analysis, increasing the urgency for mitigation. The vulnerability is categorized under CWE-434, which concerns unrestricted file upload vulnerabilities that allow dangerous file types to be uploaded without proper validation or sanitization.

For European organizations, this vulnerability poses a significant risk, especially for those relying on WordPress websites with the CSV Me plugin installed. Successful exploitation could lead to full compromise of the affected web server, resulting in data breaches, defacement, service disruption, or use of the server as a pivot point for further attacks within the corporate network. Organizations in sectors such as finance, healthcare, government, and e-commerce are particularly at risk due to the sensitive nature of their data and the criticality of their online services. The ability to execute arbitrary code remotely could also facilitate ransomware deployment or espionage activities. Since the vulnerability requires administrative access, the impact is amplified if attackers gain such credentials through phishing or insider threats. The lack of a patch means that affected organizations must rely on compensating controls until a fix is available. Given the widespread use of WordPress in Europe, the potential attack surface is large, and the impact could be severe if exploited at scale.

Immediately audit WordPress installations to identify the presence of the CSV Me plugin and its version. Remove or disable the plugin if it is not essential. Restrict administrative access to WordPress dashboards through IP whitelisting, VPN access, or multi-factor authentication (MFA) to reduce the risk of credential compromise. Implement strict file upload restrictions at the web server or application firewall level to block potentially dangerous file types such as PHP, ASP, or other executable scripts. Monitor web server logs and WordPress activity logs for unusual file upload attempts or changes to plugin files. Use a Web Application Firewall (WAF) with custom rules to detect and block attempts to exploit file upload vulnerabilities. Regularly update all WordPress plugins and core installations as soon as patches become available from the vendor. Educate administrators on phishing risks and enforce strong password policies to prevent unauthorized access. Consider deploying intrusion detection/prevention systems (IDS/IPS) that can identify exploitation attempts targeting file upload vulnerabilities. Backup website data frequently and ensure backups are stored securely offline to enable recovery in case of compromise.
