CVE-2025-67925 is a Remote File Inclusion (RFI) vulnerability identified in the PHP theme product Corpkit by zozothemes, affecting versions up to 2.0. The vulnerability stems from improper validation and control of filenames used in PHP include or require statements, which allows an attacker to supply a crafted filename parameter that references a remote malicious PHP file. When the vulnerable application includes this remote file, the attacker's code executes in the context of the web server, leading to remote code execution (RCE). This can allow attackers to execute arbitrary commands, escalate privileges, steal sensitive data, or pivot within the network. The vulnerability is particularly dangerous because it does not require authentication or user interaction, making exploitation straightforward once the vulnerable endpoint is identified. Although no public exploits or patches are currently available, the flaw is classified as a critical security issue due to its impact and ease of exploitation. The vulnerability affects Corpkit versions up to 2.0, a PHP theme product commonly used in content management systems and e-commerce websites. The lack of a CVSS score necessitates a severity assessment based on impact and exploitability factors. The vulnerability compromises confidentiality, integrity, and availability of affected systems, with a broad scope given the widespread use of PHP web applications. The vulnerability was published on January 8, 2026, with the initial reservation date in December 2025. No known exploits in the wild have been reported yet, but the risk remains high given the nature of RFI vulnerabilities.

The impact of CVE-2025-67925 on European organizations can be severe, especially for those relying on PHP-based web applications using the Corpkit theme. Successful exploitation can lead to full remote code execution, allowing attackers to take control of web servers, access sensitive customer and business data, modify website content, or use the compromised server as a pivot point for further attacks within the corporate network. This can result in data breaches, service disruptions, reputational damage, and regulatory penalties under GDPR. Public-facing websites and e-commerce platforms are particularly at risk, as attackers can exploit the vulnerability to inject malicious payloads, deface websites, or deploy ransomware. The absence of authentication requirements lowers the barrier to exploitation, increasing the likelihood of attacks. Additionally, the vulnerability could be leveraged to distribute malware to European users or to conduct espionage against strategic sectors. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that use Corpkit or derivative PHP themes face heightened risks. The potential for widespread impact is amplified by the common use of PHP in European web hosting environments.

To mitigate CVE-2025-67925, organizations should immediately audit their web applications to identify any use of the Corpkit theme up to version 2.0. Since no official patches are currently available, temporary mitigations include disabling or restricting the vulnerable include/require functionality by implementing strict input validation and sanitization on all parameters controlling file inclusion. Employ whitelisting of allowed file paths and disallow remote file inclusion by disabling allow_url_include and allow_url_fopen directives in the PHP configuration. Web application firewalls (WAFs) should be configured to detect and block suspicious file inclusion patterns and remote URL requests. Monitoring web server logs for unusual requests referencing external URLs or unexpected file paths can help detect exploitation attempts. Organizations should also isolate vulnerable systems from critical networks until a patch is released. Once vendor patches or updates become available, they must be applied promptly. Additionally, conducting regular security assessments and penetration testing focused on file inclusion vulnerabilities will help identify and remediate similar issues proactively.
