This vulnerability in Mikado-Themes Mikado Core arises from improper validation of filenames used in PHP include or require statements, enabling local file inclusion (LFI). An attacker with limited privileges can exploit this to include and execute arbitrary files on the server, potentially leading to full system compromise or denial of service. The issue affects versions up to and including 1.6. The CVSS 3.1 vector indicates network attack vector, high attack complexity, low privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to read sensitive files, execute arbitrary code, or disrupt service availability on affected Mikado Core installations. The high CVSS score reflects the potential for significant compromise of system confidentiality, integrity, and availability. However, no known active exploitation has been reported.
