The vulnerability identified as CVE-2026-28097 affects ThemeREX Artrium through improper control of filenames used in PHP include or require statements. This weakness can lead to PHP Local File Inclusion, where an attacker may include unintended files on the server, potentially leading to code execution or data disclosure. The issue impacts versions up to and including 1.0.14. The CVSS 3.1 base score is 8.1, reflecting network attack vector, high complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can result in full compromise of the affected system, including unauthorized disclosure of sensitive information, modification of data, and disruption of service. Given the high CVSS score and the nature of local file inclusion, attackers could execute arbitrary code or access critical files on the server hosting ThemeREX Artrium.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or workaround information is provided, users should monitor ThemeREX communications for updates.
