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 Fleur fleur allows PHP Local File Inclusion.This issue affects Fleur: from n/a through <= 2.2.1.

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 vulnerability in Mikado-Themes Fleur theme allows attackers to include local PHP files via unsanitized user input in include/require statements, potentially exposing sensitive system files or executing arbitrary PHP code.

MitigationImplement strict input validation and whitelist-based filtering for any file paths used in include/require statements; upgrade to a patched version if available from the vendor.

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 MikadoThemes Fleur theme is installed
    Locate theme files by searching for 'fleur' or ' Fleur' directory names in the wp-content/themes/ folder (for WordPress) or the themes/ folder of the Mikado framework installation
    Affected if The Fleur theme directory exists on the server
  2. Identify the installed Fleur theme version
    Check theme style.css or version.php files within the Fleur theme folder for a 'Version:' comment or $version variable
    Affected if The discovered version matches or predates any known vulnerable version range for this theme
  3. Locate include/require statements using dynamic input
    Search PHP files in the theme for patterns like 'include($_GET', 'require($_POST', 'include($', or similar unsanitized variable usage in include/require statements
    Affected if Dynamic file inclusion code using user-supplied input is found without sanitization
  4. Identify the vulnerable parameter input points
    Review the identified include/require code to determine which GET/POST parameters accept file paths
    Affected if Parameters like 'file', 'path', 'page', 'template', or similar are used in dynamic includes without validation
  5. Verify web access to vulnerable parameters
    Test if the parameter endpoints are accessible via HTTP/HTTPS requests with malicious path values (e.g., ../../../../etc/passwd)
    Affected if The application processes the input and returns file contents or include/require behavior
  6. Check for sensitive file exposure
    Attempt to include known system files (e.g., /etc/passwd, wp-config.php) via the identified parameters to confirm LFI exists
    Affected if Sensitive file contents are returned or the PHP code is executed

The environment is affected if the Fleur theme is installed, contains dynamic include/require code using unsanitized user input, and that input is accessible via web requests.
