Vulnerability Details

The CVE-2026-22370 vulnerability is described as an 'Improper Control of Filename for Include/Require Statement in PHP Program', also known as a 'PHP Remote File Inclusion' vulnerability. This flaw allows for PHP local file inclusion in the axiomthemes Marveland theme, affecting versions from n/a to 1.3.0.

The CVSS score of 8.1 indicates a high severity level, reflecting the potential impact on confidentiality, integrity, and availability. As noted, the attack vector is network-based, and the attack complexity is high, requiring no privileges or user interaction for exploitation.

The vulnerability falls under CWE-98, which refers to 'Improper Control of Filename for Include/Require Statement in PHP Program'. This classification highlights the inherent risks of including files without proper validation and control.

Technical Analysis

The root cause of CVE-2026-22370 is the failure to properly control the filename used in the include/require statements within the PHP code of the Marveland theme. This oversight allows attackers to exploit the system by manipulating the file path to include unauthorized files.

The attack vector is network-based, meaning that an attacker would need to send a specially crafted request to the web application hosting the vulnerable theme. The attack complexity is classified as high, indicating that the exploitation may require knowledge of the application structure and the server environment.

No privileges are required for exploitation, and user interaction is not necessary. The impacts of this vulnerability are significant, as it can lead to high confidentiality, integrity, and availability impacts, potentially compromising sensitive data and the overall functionality of the application.

Risk & Impact Analysis

The deployment of the axiomthemes Marveland theme in production environments introduces significant risk due to CVE-2026-22370. Organizations using affected versions face potential unauthorized access to sensitive files, which could lead to data breaches or service disruptions.

This vulnerability highlights the critical importance of maintaining secure coding practices and ensuring that all file inclusion mechanisms are properly validated. Given the high CVSS score, organizations should immediately address this vulnerability as part of their patch management processes.

As the situation evolves, organizations should monitor for updates from the vendor and consider implementing additional security measures such as firewalls and intrusion detection systems to mitigate potential exploitation.

Exploitation Status
