CVE-2025-67515 is a vulnerability identified in the Mikado-Themes Wilmër WordPress theme, affecting versions prior to 3.5. The issue arises from improper control over the filename parameter used in PHP include or require statements, which leads to a Local File Inclusion (LFI) vulnerability. LFI vulnerabilities allow attackers to trick the application into including files from the local filesystem, potentially exposing sensitive information such as configuration files, password files, or application source code. In some cases, LFI can be leveraged to achieve remote code execution if combined with other vulnerabilities or misconfigurations, such as log poisoning or upload of malicious files. The vulnerability is due to insufficient validation or sanitization of user-supplied input that controls the filename in include/require calls. Although no public exploits are currently known, the vulnerability is classified as published and should be considered a serious risk. The affected product, Wilmër, is a WordPress theme developed by Mikado-Themes, which is used by various websites, including those in Europe. The absence of a CVSS score indicates that the vulnerability is newly disclosed and not yet fully assessed. However, the nature of LFI vulnerabilities typically allows attackers to read arbitrary files and potentially execute code, making this a critical security concern. The vulnerability requires no authentication, increasing its risk profile. No official patches or mitigation links are currently available, emphasizing the need for immediate attention from site administrators.

For European organizations, this vulnerability poses a significant threat to the confidentiality, integrity, and availability of their web assets. Exploitation could lead to unauthorized disclosure of sensitive data such as credentials, personal information, or internal configuration files. Attackers might also leverage the vulnerability to execute arbitrary code on the web server, potentially gaining full control over the affected system. This could result in website defacement, data theft, ransomware deployment, or use of the compromised server as a pivot point for further attacks within the network. Organizations relying on the Wilmër theme for their WordPress sites, especially those handling sensitive customer or business data, face increased risk of reputational damage and regulatory penalties under GDPR if personal data is exposed. The lack of authentication requirement and ease of exploitation further exacerbate the potential impact. Additionally, the vulnerability could disrupt business operations by causing website downtime or service interruptions.

1. Monitor Mikado-Themes official channels for patches addressing CVE-2025-67515 and apply updates immediately upon release. 2. Until a patch is available, restrict access to vulnerable endpoints by implementing strict input validation and sanitization on all parameters controlling file inclusion. 3. Employ a Web Application Firewall (WAF) with rules designed to detect and block LFI attack patterns, such as suspicious file path traversal sequences. 4. Disable PHP functions that facilitate file inclusion from user input where possible, or configure PHP to restrict include paths using open_basedir directives. 5. Conduct thorough security audits of WordPress installations using Wilmër to identify any signs of compromise or exploitation attempts. 6. Limit file permissions on the web server to prevent unauthorized reading of sensitive files. 7. Educate web administrators and developers about secure coding practices related to file inclusion and input handling. 8. Maintain regular backups of website data and configurations to enable rapid recovery in case of compromise.
