This vulnerability in AncoraThemes Parkivia arises from improper validation or control of filenames used in PHP include or require statements, enabling PHP Local File Inclusion. This can allow an attacker to include and execute arbitrary local files on the server, potentially leading to remote code execution or disclosure of sensitive information. The issue affects all versions through 1.1.9. The CVSS 3.1 vector indicates network attack vector, high attack complexity, no privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability.

Successful exploitation can result in full compromise of the affected system's confidentiality, integrity, and availability. Attackers could execute arbitrary code or access sensitive files on the server. No known exploits are currently reported in the wild.
