Vulnerability Details
This vulnerability allows PHP Local File Inclusion due to improper control of the filename for include/require statements in PHP programs. The vulnerability affects Gridiron versions from n/a through <= 1.0.14. The CVSS score of 8.1 indicates a high severity level, emphasizing the importance of swift remediation.
The vulnerability is classified under CWE-98, which pertains to 'Improper Control of Filename for Include/Require Statement in PHP Program.' This classification highlights the specific nature of the flaw, indicating that it arises from insufficient validation of user-supplied input.
Technical Analysis
The root cause of CVE-2026-28012 lies in how the Gridiron theme processes include/require statements. By failing to properly validate the filenames provided in these statements, an attacker could potentially manipulate the input to include arbitrary PHP files from the server.
The attack vector for this vulnerability is network-based, meaning it can be exploited remotely without requiring physical access to the system. The attack complexity is rated as high, indicating that attackers may need to devise specific methods to exploit this flaw effectively.
No privileges are required to exploit this vulnerability, making it particularly dangerous as it can be executed without any form of authentication. User interaction is not necessary, which allows attackers to exploit the vulnerability seamlessly.
The confidentiality, integrity, and availability impacts are all rated as high, meaning successful exploitation could lead to severe breaches of sensitive data, unauthorized modifications, and potential denial of service.
Risk & Impact Analysis
The real-world risk associated with CVE-2026-28012 is significant, particularly for organizations that rely on the ThemeREX Gridiron theme for their web applications. Attackers may leverage this vulnerability to gain unauthorized access to sensitive data, leading to potential data breaches, reputational damage, and legal implications.
Organizations should assess their exposure to this vulnerability, especially if they are using the affected versions of the Gridiron theme. The potential blast radius could be extensive, impacting not only the immediate system but also interconnected environments.
Given the CVSS score of 8.1, it is critical for organizations to prioritize remediation in their patch cycles. The deferred status does not negate the necessity for immediate action, as the exploitation potential remains.
