Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in VanKarWai Airtifact airtifact allows PHP Local File Inclusion.This issue affects Airtifact: from n/a through <= 1.2.91.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

VanKarWai Airtifact up to version 1.2.91 contains a PHP Local File Inclusion (LFI) vulnerability caused by improper control of filename parameters in include/require statements. Attackers can manipulate file path inputs to include arbitrary files from the server filesystem, potentially exposing sensitive configuration files, credentials, or source code.

MitigationImplement strict input validation using an allowlist approach for all file inclusion operations. Replace dynamic file inclusion with hardcoded includes or use basename() with validated allowlist checking. Disable allow_url_include and restrict file system access permissions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify VanKarWai Airtifact installation
    Search for files or directories named 'VanKarWai', 'Airtifact', or related application files in the web root or application directories. Check for PHP files containing references to 'VanKarWai' or 'Airtifact' in headers or comments.
    Affected if The application is present in the environment and is named VanKarWai Airtifact.
  2. Determine the installed version
    Locate version information in the application - check for version.php, about.php, README files, configuration files, or a changelog file within the application directory. Compare the found version against the affected range of up to 1.2.91.
    Affected if The installed version is 1.2.91 or any earlier version.
  3. Locate PHP file inclusion functions
    Search the application source code for dynamic usage of include, require, include_once, require_once, or similar functions where the file path is not a hardcoded string. Look for patterns like include($_GET['...']) or require($var) in PHP files.
    Affected if Dynamic file inclusion functions are found where user input could control the file path.
  4. Examine input sources for file inclusion
    Trace the variables passed to include/require statements back to their origin. Check if they receive input from $_GET, $_POST, $_REQUEST, or other user-controllable sources without proper sanitization.
    Affected if User-controllable parameters can reach file inclusion functions without validation.
  5. Check for proper input validation
    Review the code handling file inclusion paths. Determine if there is allowlist validation, basename() usage with allowlist checking, or if the input is used directly in the include/require statement.
    Affected if File inclusion parameters accept arbitrary file paths without allowlist validation or sanitization.

The environment is affected if VanKarWai Airtifact version 1.2.91 or earlier is installed and contains PHP file inclusion code that accepts unsanitized user input to control which files are included.
