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 Mikado-Themes Holmes holmes allows PHP Local File Inclusion.This issue affects Holmes: from n/a through <= 1.7.

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

Local File Inclusion (LFI) vulnerability in the Mikado-Themes Holmes WordPress theme (version <= 1.7) allows attackers to include arbitrary local PHP files due to improper control of filename parameters in include/require statements, potentially leading to remote code execution.

MitigationUpdate the Holmes theme to the latest patched version. If no patch is available, disable the theme and implement input validation with allowlist filtering on all file inclusion functions to prevent path traversal.

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. Confirm Holmes theme installation
    Search the web server for files belonging to the Holmes theme by Mikado-Themes (typically found in wp-content/themes/holmes for WordPress or similar theme directories)
    Affected if The Holmes theme by Mikado-Themes is present on the server
  2. Locate include/require statements
    Search the theme's PHP files for include, require, include_once, or require_once statements that accept variable file paths (e.g., include($file), require($_GET['path']))
    Affected if Dynamic file includes using variables or user input are found in the theme code
  3. Identify file path parameter source
    Examine the identified include/require calls to determine if the file path is derived from HTTP request parameters (GET/POST), cookies, or other user-controllable input
    Affected if The file path passed to include/require originates from user-supplied input without validation
  4. Verify allowlist absence
    Review the code around the vulnerable include/require to check if an allowlist or fixed base path is used to restrict which files can be included
    Affected if No input validation, allowlist, or fixed base path is implemented for the file inclusion
  5. Test parameter accessibility
    Attempt to access the suspected vulnerable parameter via HTTP request (e.g., ?file=../../../../etc/passwd) to confirm it reaches the vulnerable code path
    Affected if The vulnerable parameter is reachable and the application processes the request

A user is affected if the Holmes theme is installed and the vulnerable include/require pattern with user-controlled file paths is present and accessible.

Update the Holmes theme to the latest patched version. If no patch is available, disable the theme and implement input validation with allowlist filtering on all file inclusion functions to prevent path traversal.
