CVE-2025-67941 is a Remote File Inclusion (RFI) vulnerability found in the Elated-Themes WordPress theme 'The Aisle' versions prior to 2.9.1. The vulnerability arises from improper validation and control of filenames used in PHP include or require statements. This flaw allows an attacker to manipulate the filename parameter to include remote PHP files, which the server then executes. Exploitation requires no authentication or user interaction but has a high attack complexity, likely due to necessary conditions such as specific server configurations or network access. Successful exploitation can lead to full compromise of the affected web server, including arbitrary code execution, data theft, defacement, or pivoting to internal networks. The CVSS 3.1 vector indicates network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits are reported in the wild, the severity and nature of the vulnerability make it a critical concern for sites using this theme. The lack of patch links suggests that users should obtain updates directly from the vendor or official theme repositories. The vulnerability is particularly relevant to WordPress sites that rely on this theme for e-commerce, blogging, or corporate presence, as remote code execution can lead to severe operational and reputational damage.

For European organizations, this vulnerability poses a significant risk to websites running the vulnerable version of The Aisle theme. Exploitation can result in unauthorized remote code execution, leading to data breaches involving personal data protected under GDPR, website defacement, service disruption, and potential lateral movement within corporate networks. Organizations in sectors such as e-commerce, media, and public services that rely on WordPress for their online presence are particularly vulnerable. The compromise of web servers can also be leveraged to launch further attacks against internal systems or customers. Given the high confidentiality, integrity, and availability impacts, affected organizations may face regulatory penalties, loss of customer trust, and operational downtime. The network-based attack vector means that public-facing websites are exposed to remote attackers without requiring user interaction or credentials, increasing the threat surface. The absence of known exploits in the wild currently provides a window for proactive mitigation before widespread exploitation occurs.

1. Immediately update The Aisle theme to version 2.9.1 or later, where the vulnerability is patched. 2. If immediate update is not possible, implement strict input validation and sanitization on any parameters controlling file includes in custom code or theme modifications. 3. Configure PHP settings to disable allow_url_include and allow_url_fopen to prevent remote file inclusion. 4. Employ a Web Application Firewall (WAF) with rules to detect and block suspicious include or require parameter manipulations. 5. Restrict PHP include paths using open_basedir to limit file inclusion to trusted directories only. 6. Regularly audit and monitor web server logs for unusual requests or errors related to file inclusion. 7. Conduct penetration testing focused on file inclusion vulnerabilities to verify remediation effectiveness. 8. Educate site administrators on the risks of outdated themes and the importance of timely patching. 9. Backup website data and configurations regularly to enable rapid recovery in case of compromise. 10. Review and harden server and WordPress security configurations to reduce attack surface.
