This vulnerability arises from improper validation or control of filenames used in PHP include or require statements within the Funnel Builder by FunnelKit plugin. It allows an attacker to perform PHP Local File Inclusion (LFI), which can lead to disclosure of sensitive files, code execution, or denial of service. The issue affects all versions up to and including 3.11.1. The CVSS 3.1 vector indicates network attack vector, high attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can lead to local file inclusion, enabling attackers to read sensitive files, execute arbitrary PHP code, or disrupt service. The high CVSS score reflects the potential for significant compromise of the affected system's confidentiality, integrity, and availability. However, exploitation requires user interaction and has high attack complexity, which may limit the ease of exploitation.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should monitor for updates from Aman or FunnelKit and consider applying any recommended temporary mitigations provided by the vendor. Avoid exposing the vulnerable plugin to untrusted users and restrict access where possible.
