CVE-2025-67934 is a vulnerability classified as an improper control of filename for include/require statements in PHP programs, specifically affecting the Mikado-Themes Wellspring WordPress theme versions prior to 2.8. The vulnerability allows an attacker to perform remote file inclusion (RFI), where they can manipulate the filename parameter used in PHP's include or require functions to load arbitrary files. This can lead to execution of malicious code on the server, enabling remote code execution (RCE). The root cause is insufficient validation or sanitization of user-controlled input that determines which files are included by the PHP script. Although the description mentions PHP Local File Inclusion, the nature of the vulnerability suggests that remote file inclusion is possible, allowing attackers to include files from remote servers. This can result in full compromise of the web server, data theft, defacement, or pivoting to internal networks. The vulnerability affects all versions of Wellspring prior to 2.8, with no patch currently available or linked. No known exploits have been reported in the wild yet, but the vulnerability is publicly disclosed and thus may attract attackers. The lack of a CVSS score requires an independent severity assessment. Given the ability to execute arbitrary code remotely without authentication, the impact on confidentiality, integrity, and availability is severe. The vulnerability is easy to exploit if the vulnerable parameter is exposed to unauthenticated users, and the scope includes any website running the affected theme. The vulnerability is critical and requires urgent remediation.

For European organizations, the impact of CVE-2025-67934 can be severe. Many European companies rely on WordPress for their websites, and Mikado-Themes is a popular theme provider, including Wellspring. Exploitation could lead to full server compromise, allowing attackers to steal sensitive customer data, intellectual property, or internal credentials. It could also enable attackers to deface websites, damaging brand reputation and customer trust. Additionally, compromised servers could be used as a foothold for further attacks within corporate networks or as part of botnets for distributed denial-of-service (DDoS) attacks. Regulatory frameworks such as GDPR impose strict data protection requirements, and a breach resulting from this vulnerability could lead to significant fines and legal consequences. The lack of known exploits currently provides a window for proactive mitigation, but the public disclosure increases the risk of imminent exploitation attempts.

1. Immediate action should be to upgrade the Wellspring theme to version 2.8 or later once the patch is released by Mikado-Themes. 2. Until an official patch is available, review and harden the theme's PHP code to ensure all include/require statements use fixed, whitelisted filenames and do not accept user input directly. 3. Implement web application firewall (WAF) rules to detect and block attempts to manipulate file inclusion parameters, such as suspicious URL patterns or payloads attempting directory traversal or remote file inclusion. 4. Restrict PHP configuration settings by disabling allow_url_include and allow_url_fopen to prevent remote file inclusion. 5. Limit file system permissions for the web server user to prevent execution or reading of unauthorized files. 6. Monitor web server logs for unusual requests targeting the vulnerable parameters. 7. Conduct regular security audits and penetration testing focusing on file inclusion vulnerabilities. 8. Educate developers and administrators about secure coding practices related to file inclusion and input validation.
