CVE-2025-58885 is a Remote File Inclusion (RFI) vulnerability identified in the AncoraThemes Pathfinder WordPress theme, affecting versions up to and including 1.16. The vulnerability stems from improper validation and control of filenames used in PHP include or require statements, which are critical functions that incorporate external PHP files into the executing script. By exploiting this flaw, an attacker can manipulate the filename parameter to include a remote malicious PHP file hosted on an attacker-controlled server. This leads to arbitrary code execution within the context of the web server, potentially allowing full system compromise. The vulnerability is classified as a Local File Inclusion (LFI) in the description but the nature of improper filename control and the mention of remote file inclusion indicates RFI capabilities. No CVSS score has been assigned yet, and no public exploits have been observed. The vulnerability was reserved in early September 2025 and published in December 2025. AncoraThemes Pathfinder is a WordPress theme used primarily for portfolio and business websites, making it a target for attackers seeking to compromise web servers for data theft, defacement, or pivoting into internal networks. The lack of patches or mitigation links indicates that users must proactively monitor for updates or apply manual code sanitization to prevent exploitation.

For European organizations, this vulnerability poses a significant risk to websites running the AncoraThemes Pathfinder theme, particularly those exposed to the internet. Successful exploitation can lead to remote code execution, allowing attackers to steal sensitive data, deploy malware, deface websites, or use compromised servers as a foothold for further attacks within corporate networks. This can disrupt business operations, damage reputation, and lead to regulatory non-compliance, especially under GDPR where data breaches must be reported. Organizations relying on WordPress for customer-facing portals, marketing sites, or internal tools are at risk. The absence of known exploits currently reduces immediate risk but also means organizations should act swiftly to prevent future attacks. The impact on confidentiality, integrity, and availability is high, as attackers can execute arbitrary code and manipulate server files without authentication or user interaction.

European organizations should immediately inventory their WordPress installations to identify the use of AncoraThemes Pathfinder theme versions up to 1.16. Until an official patch is released, administrators should implement strict input validation and sanitization on any parameters controlling file includes in the theme code, ensuring only trusted local files can be included. Employing Web Application Firewalls (WAFs) with rules to detect and block suspicious file inclusion attempts can provide interim protection. Restricting PHP functions such as allow_url_include and disabling remote file inclusion in php.ini can mitigate exploitation risk. Regularly monitoring web server logs for unusual requests targeting include parameters is recommended. Organizations should subscribe to AncoraThemes and security mailing lists for timely patch announcements and apply updates immediately upon release. Additionally, isolating WordPress instances in segmented network zones limits lateral movement if compromise occurs.
