This vulnerability in AncoraThemes Festy arises from improper validation or control of filenames in PHP include or require statements, leading to PHP Local File Inclusion. It affects versions up to and including 1.13.0. The CVSS 3.1 vector indicates the attack requires network access with high attack complexity, no privileges, and no user interaction, and impacts confidentiality, integrity, and availability with high severity. No vendor advisory or patch information is available to confirm remediation status.

Successful exploitation could allow an attacker to include and execute arbitrary local files on the affected server, potentially leading to full compromise of confidentiality, integrity, and availability of the system running AncoraThemes Festy. This could result in unauthorized data access, code execution, and service disruption.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting access to vulnerable endpoints, applying web application firewall rules to detect and block suspicious include/require requests, and limiting file system permissions to reduce impact.
