This vulnerability arises from improper validation or control of filenames used in PHP include or require statements within the nicdark Hotel Booking application (up to version 3.7). It enables a PHP Local File Inclusion attack, where an attacker can cause the application to include unintended files, potentially leading to arbitrary code execution or disclosure of sensitive information. The CVSS vector indicates network attack vector, high attack complexity, low privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability.

Successful exploitation can lead to full compromise of the affected system by allowing an attacker to execute arbitrary code or access sensitive files. The vulnerability impacts confidentiality, integrity, and availability of the system. No known exploits have been reported in the wild so far.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should restrict access to the affected application and consider disabling or restricting the vulnerable functionality if possible.
