CVE-2025-69057 is a remote file inclusion (RFI) vulnerability found in the Edge-Themes Eldon PHP theme, specifically affecting versions up to 1.0. The vulnerability arises from improper validation and control of filenames used in PHP include or require statements, which allows an attacker to specify a remote file to be included and executed by the PHP interpreter. This type of vulnerability enables attackers to execute arbitrary PHP code on the target server remotely without requiring authentication or user interaction. The CVSS v3.1 base score of 8.1 reflects the high impact on confidentiality, integrity, and availability, combined with network attack vector and high attack complexity. The vulnerability can lead to full system compromise, data theft, defacement, or use of the server as a pivot point for further attacks. Although no public exploits are currently known, the nature of RFI vulnerabilities makes them attractive targets for attackers. The vulnerability affects websites and applications using the Eldon theme, which is used primarily in WordPress or other PHP-based CMS environments. The lack of available patches at the time of publication necessitates immediate mitigation efforts to prevent exploitation.

For European organizations, exploitation of CVE-2025-69057 could result in severe consequences including unauthorized access to sensitive data, website defacement, disruption of services, and potential lateral movement within corporate networks. Organizations relying on the Eldon theme for their web presence, particularly in sectors such as e-commerce, finance, and government, face risks of data breaches and reputational damage. The ability to execute arbitrary code remotely without authentication increases the likelihood of automated exploitation attempts. Given the widespread use of PHP-based CMS platforms in Europe, the vulnerability could affect a broad range of businesses and public sector entities. Additionally, compromised web servers could be leveraged to launch attacks against other internal or external targets, amplifying the threat. The impact is heightened in countries with large digital economies and extensive online services, where downtime or data loss can have significant economic and regulatory repercussions.

Organizations should immediately audit their web environments to identify installations of the Edge-Themes Eldon theme, particularly versions up to 1.0. Until an official patch is released, mitigation should include disabling or removing the vulnerable theme to prevent exploitation. Implement strict input validation and sanitization for any user-supplied parameters that influence file inclusion paths. Employ web application firewalls (WAFs) configured to detect and block remote file inclusion attempts and suspicious URL patterns. Restrict outbound HTTP requests from web servers to prevent fetching remote malicious files. Monitor web server logs for unusual inclusion attempts or errors indicative of exploitation attempts. Regularly update all CMS components and themes to their latest versions once patches become available. Conduct security awareness training for developers and administrators on secure coding practices related to file inclusion. Finally, consider deploying runtime application self-protection (RASP) solutions to detect and block exploitation in real time.
