CVE-2025-64230 is a path traversal vulnerability identified in the WP Chill Filr plugin for WordPress, specifically in versions up to and including 1.2.10. The vulnerability arises from improper limitation of pathnames to restricted directories, allowing an attacker to manipulate file paths and access files outside the intended directory scope. This flaw enables remote attackers to read arbitrary files on the web server without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The vulnerability impacts confidentiality severely (C:H), but does not affect integrity or availability. Exploitation involves sending crafted requests that traverse directory paths (e.g., using ../ sequences) to access sensitive files such as configuration files, credentials, or other protected data stored on the server. Although no known exploits are currently reported in the wild, the ease of exploitation and the potential impact make this a critical concern for sites using the Filr plugin. The vulnerability was reserved in late October 2025 and published in December 2025, with no official patches currently linked, indicating that users must monitor vendor updates closely. The plugin’s role in file management or protection within WordPress sites means that compromised confidentiality could lead to further attacks or data breaches. The vulnerability’s network attack vector and lack of required privileges make it a high-risk issue for exposed WordPress installations.

For European organizations, the primary impact of CVE-2025-64230 is the unauthorized disclosure of sensitive information stored on web servers running the vulnerable WP Chill Filr plugin. This could include configuration files, database credentials, user data, or proprietary information, potentially leading to further compromise or data breaches. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, face significant compliance risks under GDPR if sensitive personal data is exposed. The vulnerability’s ease of exploitation means attackers can quickly gain access without authentication, increasing the risk of widespread attacks on vulnerable WordPress sites. Additionally, compromised sites could be used as footholds for lateral movement within networks or for launching further attacks. The lack of integrity or availability impact limits the threat to data confidentiality, but the exposure of sensitive files alone can have severe operational and reputational consequences. European organizations relying on WordPress and the Filr plugin should consider this vulnerability a high priority for remediation to avoid potential data leaks and regulatory penalties.

1. Immediately monitor WP Chill’s official channels for patches addressing CVE-2025-64230 and apply updates as soon as they become available. 2. Until patches are released, implement strict web server access controls to restrict access to sensitive directories and files, using .htaccess rules or equivalent configurations. 3. Employ Web Application Firewalls (WAF) with custom rules to detect and block path traversal attack patterns, such as requests containing '../' sequences. 4. Conduct thorough audits of WordPress installations to identify the presence and versions of the Filr plugin and remove or disable the plugin if not essential. 5. Limit file permissions on the server to the minimum necessary, preventing the web server process from reading sensitive files outside designated directories. 6. Monitor server logs for unusual file access attempts or anomalies indicative of exploitation attempts. 7. Educate site administrators about the risks of outdated plugins and enforce strict update policies. 8. Consider isolating WordPress instances in segmented network zones to reduce potential lateral movement if compromised.
