CVE-2025-67937 is a vulnerability identified in the Mikado-Themes Hendon WordPress theme, specifically affecting versions prior to 1.7. The issue arises from improper control over the filename used in PHP include or require statements, which leads to a Local File Inclusion (LFI) vulnerability. LFI vulnerabilities occur when an application allows user-supplied input to dictate which files are included or required by the PHP interpreter without proper validation or sanitization. In this case, an attacker can manipulate the input to include arbitrary files from the server's filesystem. This can lead to exposure of sensitive information such as configuration files, source code, or credentials. In some scenarios, LFI can be leveraged to execute arbitrary code, especially if combined with other vulnerabilities or if the attacker can upload malicious files. The vulnerability affects the Hendon theme before version 1.7, with no patch links currently provided. No known exploits are publicly reported yet, but the flaw is publicly disclosed and documented in the CVE database. The vulnerability does not require authentication or user interaction, making it easier for remote attackers to exploit. The absence of a CVSS score necessitates an assessment based on the impact and exploitability factors.

For European organizations using WordPress sites with the Mikado-Themes Hendon theme, this vulnerability poses a significant risk. Exploitation could lead to unauthorized disclosure of sensitive data stored on web servers, including database credentials, internal configuration files, or user data, compromising confidentiality. Attackers might also achieve remote code execution, leading to full site compromise, defacement, or use of the server as a pivot point for further attacks within the network, impacting integrity and availability. This could result in reputational damage, regulatory penalties under GDPR for data breaches, and operational disruptions. The impact is particularly critical for organizations in sectors such as finance, healthcare, government, and e-commerce, where website integrity and data confidentiality are paramount. Since WordPress is widely used across Europe, and Mikado-Themes is a popular theme provider, the scope of affected systems could be substantial if the theme is not updated promptly.

1. Immediately check if the Hendon theme is in use on your WordPress sites and identify the version. 2. Monitor Mikado-Themes official channels for patches or updates addressing this vulnerability and apply them as soon as they become available. 3. If no official patch is available, implement manual mitigations by reviewing and sanitizing all inputs that influence include or require statements in the theme's PHP code, ensuring only intended files can be included. 4. Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious file inclusion attempts or unusual URL parameters. 5. Restrict file system permissions on web servers to limit access to sensitive files and directories, reducing the impact of potential LFI exploitation. 6. Conduct regular security audits and vulnerability scans focusing on WordPress themes and plugins. 7. Educate site administrators on the risks of using outdated themes and the importance of timely updates. 8. Implement monitoring and alerting for anomalous web server activity that could indicate exploitation attempts.
