The vulnerability CVE-2026-39611 affects kutethemes KuteShop (<= 4.2.9) and is caused by improper control of the filename parameter in PHP include or require statements. This leads to a PHP Local File Inclusion issue, potentially allowing an attacker to include and execute arbitrary local files on the server. The vulnerability is documented but lacks a CVSS score and vendor remediation details. It is not a cloud service, and no known exploits have been reported.

Successful exploitation of this vulnerability could allow an attacker to include local files on the server, which may lead to information disclosure, code execution, or other unauthorized actions depending on the server configuration and included files. The exact impact depends on the environment and usage but generally poses a significant risk to affected systems.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting access to vulnerable endpoints, applying web application firewalls with rules targeting file inclusion attempts, and reviewing application code for unsafe include/require usage.
