CVE-2025-14359 is a vulnerability classified as improper control of filename for include/require statements in PHP within the brandexponents Oshine WordPress theme, affecting versions up to 7.2.7. This flaw enables remote file inclusion (RFI) or local file inclusion (LFI), where an attacker can manipulate the input to PHP include or require functions to load arbitrary files. This can lead to execution of malicious code, disclosure of sensitive files, or full site compromise. The vulnerability stems from insufficient validation or sanitization of user-supplied input that determines which files are included by the PHP application. Although the CVSS score is not provided, the vulnerability is critical because it allows unauthenticated attackers to execute arbitrary code remotely, potentially gaining control over the web server. No patches or exploits are currently documented, but the risk is high given the widespread use of the Oshine theme in WordPress environments. The vulnerability affects the confidentiality, integrity, and availability of affected systems, and exploitation does not require user interaction or authentication. The lack of patch links suggests that vendors or maintainers have yet to release a fix, increasing urgency for mitigation.

For European organizations, especially those relying on WordPress websites using the Oshine theme, this vulnerability could lead to severe consequences including unauthorized access, data theft, website defacement, and service outages. Attackers could deploy web shells or malware, compromising customer data and intellectual property, damaging brand reputation, and causing regulatory compliance issues under GDPR. E-commerce platforms and media companies are particularly at risk due to their reliance on web presence and customer trust. The vulnerability could also be leveraged as a foothold for lateral movement within corporate networks. Given the potential for remote code execution without authentication, the impact on confidentiality, integrity, and availability is substantial. Organizations may face financial losses, legal penalties, and operational disruptions if exploited.

Organizations should immediately audit their WordPress installations to identify use of the Oshine theme, particularly versions up to 7.2.7. Until a vendor patch is released, administrators should implement strict input validation and sanitization on any user-supplied data that influences file inclusion. Employing web application firewalls (WAFs) with rules to detect and block suspicious file inclusion attempts is critical. Disabling PHP functions such as allow_url_include and allow_url_fopen in the PHP configuration can reduce risk. Regular backups and monitoring for unusual file changes or webshell indicators will aid in early detection. Organizations should subscribe to vendor advisories for timely patch releases and apply updates promptly. Restricting file permissions and isolating web server environments can limit damage if exploitation occurs. Finally, conducting penetration testing focused on file inclusion vulnerabilities can help identify residual risks.
