The vulnerability CVE-2026-39623 affects the kutethemes Biolife PHP application (versions up to 3.2.3) due to improper validation or control of filenames used in include or require statements. This can lead to Local File Inclusion, where an attacker can cause the application to include unintended files, potentially leading to code execution or information disclosure. The CVSS 3.1 base score is 7.5, reflecting network attack vector, high attack complexity, low privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. The vulnerability is publicly known but lacks an official patch or vendor remediation at this time.

Successful exploitation of this vulnerability could allow an attacker to include local files on the server, potentially leading to arbitrary code execution, information disclosure, or denial of service. The high CVSS score indicates that the impact on confidentiality, integrity, and availability is significant. However, there are no known active exploits reported in the wild currently.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should restrict access to vulnerable endpoints, apply strict input validation or filtering on filename parameters if possible, and monitor for suspicious activity related to file inclusion attempts. Avoid exposing the application to untrusted networks or users where feasible.
