NVD · unedited
Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in Mikado-Themes Belfort belfort allows PHP Local File Inclusion.This issue affects Belfort: from n/a through <= 1.0.

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

A PHP Local File Inclusion vulnerability exists in the Belfort theme by Mikado-Themes where user-supplied input is used in include/require statements without proper validation. This allows attackers to potentially read sensitive files or execute arbitrary PHP code on the server.

MitigationSince the Belfort theme appears to be abandoned (no version beyond 1.0), the recommended remediation is to replace or remove the theme entirely; if continued use is required, locate and sanitize all include/require statements to validate file paths against an allowlist.

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 Belfort theme files
    Search the web root directory for files belonging to the Belfort theme by Mikado-Themes. Common paths include /wp-content/themes/belfort/ (if WordPress) or /themes/belfort/. Look for files like header.php, footer.php, or any custom PHP files in the theme directory.
    Affected if The Belfort theme directory exists on the server and is actively loaded by the web application.
  2. Determine theme version
    Check for a style.css or theme.json file within the Belfort theme directory. Open the file and look for a 'Version:' header or 'version' field. Compare this version to any known versions (note: the theme appears to have no version beyond 1.0).
    Affected if The installed version is the Belfort theme by Mikado-Themes, regardless of version number.
  3. Identify include/require statements using user input
    In the Belfort theme directory, search all PHP files for patterns like 'include($_GET[', 'require($_GET[', 'include($_POST[', 'require($_POST[', or similar where $_GET, $_POST, $_REQUEST, or $_COOKIE superglobals are used directly in include/require statements without sanitization.
    Affected if Any PHP file in the theme contains include/require statements that incorporate unsanitized user-supplied input from request parameters.
  4. Verify vulnerable code is accessible
    If suspicious include/require patterns are found, test whether the affected parameters (e.g., a specific query string parameter used in the include) can be passed via HTTP requests. Attempt to manipulate the parameter to include a known file path (e.g., ../../wp-config.php for WordPress) to confirm the LFI is exploitable.
    Affected if The vulnerable include/require parameter is exposed via URL or form input and allows path traversal (e.g., using ../ to access files outside the theme directory).

A user is affected if the Belfort theme by Mikado-Themes is installed and any PHP file in the theme uses include/require with unsanitized user input that is accessible via HTTP requests.
