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 ThemeREX MCKinney's Politics mckinney-politics allows PHP Local File Inclusion.This issue affects MCKinney's Politics: from n/a through <= 1.2.8.

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

This is a file inclusion vulnerability in the ThemeREX MCKinney's Politics WordPress theme (version <= 1.2.8) where improper control of filename parameters in PHP include/require statements allows attackers to include arbitrary local or potentially remote PHP files, leading to remote code execution.

MitigationUpdate to the latest patched version of MCKinney's Politics theme; if unavailable, implement web application firewall rules to block directory traversal patterns and validate/sanitize all file inclusion parameters, or disable the theme until a patch is released.

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. Locate the MCKinney's Politics theme directory
    Check the wp-content/themes/ directory for a folder named 'politics' or 'mckinney-politics' or similar naming patterns associated with the ThemeREX MCKinney's Politics theme
    Affected if The theme directory exists in the WordPress installation's theme folder
  2. Identify the theme version from style.css
    Open the theme's style.css file and look for the 'Version:' declaration in the file header comments
    Affected if The declared version number is 1.2.8 or lower (the vulnerability affects versions up to and including 1.2.8)
  3. Inspect PHP files for vulnerable include/require patterns
    Search theme PHP files for include(), require(), include_once(), or require_once() statements where variables are used in the file path without proper sanitization (e.g., include($file), require($_GET['page']))
    Affected if Unsanitized file inclusion functions using variable or user-controlled input are found in the theme's PHP code
  4. Test for LFI/RFI via HTTP parameters
    If identifiable, attempt a controlled test request to suspected endpoints with a benign path traversal pattern (e.g., ?file=../../index) to see if the application reflects file contents
    Affected if The application returns file contents from arbitrary paths or the parameter is not properly validated

The environment is affected if the MCKinney's Politics theme version is 1.2.8 or lower and the theme contains vulnerable file inclusion code accessible via web requests
