This vulnerability (CVE-2025-69174) affects ThemeREX Etude versions <=1.6 and involves improper control of filenames in PHP include/require statements, categorized as CWE-98. It allows unauthenticated attackers to perform local file inclusion, potentially leading to remote file inclusion attacks. The CVSS 3.1 base score is 8.1, indicating high severity with network attack vector, high impact on confidentiality, integrity, and availability, and no privileges or user interaction required. No known exploits in the wild or vendor patches have been reported as of the publication date.

Successful exploitation can lead to remote file inclusion, allowing an attacker to execute arbitrary code remotely, compromising confidentiality, integrity, and availability of the affected system. Since the vulnerability is unauthenticated and remotely exploitable, it poses a significant risk to affected installations.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to vulnerable installations and consider disabling or restricting PHP include/require functionality if feasible.
