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 themelexus Kitchor kitchor allows PHP Local File Inclusion.This issue affects Kitchor: from n/a through <= 1.4.3.

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 · moderate confidence

The themelexus Kitchor theme versions 1.4.3 and below contain a PHP Local File Inclusion (LFI) vulnerability where user-supplied input is improperly used in include/require statements without sufficient validation. An attacker can manipulate filename parameters to include arbitrary local PHP files, potentially achieving remote code execution if they can upload files or access sensitive system files.

MitigationAudit and sanitize all include/require statements to use allowlisted file paths, implement strict input validation, and consider removing dynamic file inclusion functionality if not essential. Upgrade to any available patched version.

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 Kitchor theme version
    Locate the theme's style.css file typically at wp-content/themes/kitchor/style.css or check the theme's version.php file and note the declared version number
    Affected if The installed version is 1.4.3 or lower
  2. Locate dynamic file inclusion code
    Search the theme's PHP files for include, require, include_once, or require_once statements that reference $_GET, $_POST, $_REQUEST, or similar user-supplied parameters without sanitization
    Affected if Any include/require statement uses unsanitized user input to construct file paths
  3. Identify the vulnerable filename parameter
    Examine the identified inclusion code to find which specific parameter (commonly 'filename', 'file', 'page', 'template', or similar) controls the included file path
    Affected if The parameter used in the include/require is directly passed from user input without validation or allowlisting
  4. Verify parameter accessibility
    Check whether the vulnerable code path is accessible to unauthenticated users by examining function wrappers, authentication checks, and the request method required to trigger the inclusion
    Affected if The file inclusion functionality can be triggered by unauthenticated users or without proper access controls

Your environment is affected if the Kitchor theme version is 1.4.3 or lower AND the theme contains include/require statements using unvalidated user-supplied filename parameters that are accessible to attackers.
