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 Creatives_Planet Emphires emphires allows PHP Local File Inclusion.This issue affects Emphires: from n/a through <= 3.9.

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 PHP Local File Inclusion (LFI) vulnerability in the Emphires theme by Creatives_Planet. The vulnerability allows attackers to include arbitrary local files on the server due to improper control of filenames in include/require statements. This can lead to sensitive data exposure, code execution, or further compromise of the system.

MitigationFix the vulnerable include/require statements by implementing strict input validation, using allowlists for permitted files, or avoiding dynamic file inclusion entirely. Upgrade to a patched version if available.

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 Emphires theme installation
    Search your web server directories for the Emphires theme files, typically found in wp-content/themes/emphires or similar theme directories
    Affected if The Emphires theme is present in the environment
  2. Determine installed version
    Check the theme's style.css or theme.json file for the version declaration, or examine any version.php or version.txt file within the theme folder
    Affected if The installed version falls within any affected range or is unknown/unpatched
  3. Identify PHP files with include/require statements
    Search the theme's PHP files for include, include_once, require, or require_once statements that accept user-supplied input (e.g., parameters from GET/POST requests)
    Affected if Dynamic file inclusion using user input is found without apparent sanitization
  4. Inspect input validation on file inclusion code
    Examine the identified include/require code paths to verify whether $_GET, $_POST, or similar superglobals are used directly as file paths, and check if basename(), realpath(), or whitelist validation is applied
    Affected if User input is used in include/require statements without sanitization functions like basename() or realpath()
  5. Confirm vulnerability is web-accessible
    Verify that the vulnerable PHP file and its input parameters are accessible via HTTP/HTTPS requests to the web server
    Affected if The vulnerable code can be reached through web requests

If the Emphires theme is installed and its PHP code contains include/require statements using unsanitized user input that is web-accessible, the environment is likely affected by this LFI vulnerability.
