The vulnerability CVE-2026-28097 affects ThemeREX Artrium versions up to 1.0.14 and is caused by improper control of filenames in PHP include or require statements. This leads to PHP Local File Inclusion, where an attacker can cause the application to include unintended files, potentially leading to remote code execution or information disclosure. The CVSS 3.1 base score is 8.1, reflecting network attack vector, high complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. No patch or remediation details are provided in the available data.

Successful exploitation of this vulnerability could allow an unauthenticated attacker to include local files on the server, potentially leading to remote code execution, data disclosure, or denial of service. The high CVSS score indicates severe impact on system confidentiality, integrity, and availability. There are no known exploits in the wild currently.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor ThemeREX communications for updates. Until a fix is available, restricting access to vulnerable endpoints and applying web application firewall rules to block suspicious include/require requests may help mitigate risk.
