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 AncoraThemes Femme femme allows PHP Local File Inclusion.This issue affects Femme: from n/a through <= 1.3.11.

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 the Femme theme by AncoraThemes allows attackers to include arbitrary local files from the server filesystem via improper control of filename parameters in PHP include/require statements. This can enable exposure of sensitive configuration files, credentials, source code, and system files.

MitigationUpdate Femme theme to the latest patched version. If no patch available, implement strict input validation using whitelist approaches for any file inclusion logic, disable allow_url_include, and ensure all user-supplied parameters are sanitized before use in include/require statements.

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 Femme theme installation
    Check your WordPress themes directory (wp-content/themes/femme) or look for 'AncoraThemes' and 'Femme' in your theme header files (style.css or theme.json)
    Affected if The Femme theme by AncoraThemes is installed on the WordPress site
  2. Identify Femme theme version
    Open the theme's style.css file in the femme theme folder and locate the 'Version:' declaration in the theme header comment
    Affected if The installed version is older than the patched version (check against the latest available version from AncoraThemes)
  3. Locate vulnerable file inclusion code
    Search PHP files in the femme theme folder for include, require, include_once, or require_once statements that use variables from $_GET, $_POST, or $_REQUEST without sanitization (e.g., grep for 'include.*\$_GET', 'require.*\$_REQUEST')
    Affected if Any PHP file contains include/require using unsanitized user input from query parameters
  4. Check for exposed template/parameter handlers
    Examine index.php, header.php, or custom PHP files that handle page template loading via URL parameters (common parameter names: template, page, file, path, theme, style)
    Affected if The theme accepts a parameter to load external files and passes it directly to include/require without validation

If the Femme theme is installed and contains PHP code that uses user-supplied input in include/require statements without validation, the environment is vulnerable to LFI attacks.
