This vulnerability in Select-Themes Moments (<= 2.2) arises from improper validation or control of filenames used in PHP include or require statements, enabling PHP Local File Inclusion. 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. The issue allows an attacker to cause the application to include local files, which can lead to sensitive information disclosure or remote code execution depending on the context.

Successful exploitation can lead to full compromise of the affected system's confidentiality, integrity, and availability. An attacker may read sensitive files or execute arbitrary code depending on the server configuration and included files. This can result in data breaches, service disruption, or further system compromise.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official patch or workaround information is provided in the available data.
