This vulnerability in ThemeREX Medeus (<= 1.14) arises from improper control of filenames in PHP include/require statements, enabling unauthenticated Local File Inclusion (LFI). The flaw allows an attacker to include arbitrary local files, which can lead to remote code execution or disclosure of sensitive information. The CVSS 3.1 base score is 8.1, reflecting high impact on confidentiality, integrity, and availability, with network attack vector, high attack complexity, no privileges required, and no user interaction needed. No official patch or remediation guidance is currently available from the vendor, and no known exploits are reported in the wild.

Successful exploitation can result in full compromise of the affected system's confidentiality, integrity, and availability. An attacker can include arbitrary local files, potentially leading to remote code execution or disclosure of sensitive data without authentication.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the affected application and monitor for suspicious activity. Avoid exposing the application to untrusted networks if possible.
