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 ThemeREX Mandala mandala allows PHP Local File Inclusion.This issue affects Mandala: from n/a through <= 2.8.

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

A PHP Local File Inclusion vulnerability in ThemeREX Mandala theme (version <= 2.8) allows attackers to include arbitrary local PHP files by manipulating file path parameters in include/require statements without proper validation.

MitigationSanitize and validate all user-supplied input used in include/require statements using allowlist-based validation, and disable allow_url_include in PHP configuration.

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. Identify if ThemeREX Mandala theme is installed
    Search the web server's themes directory (typically wp-content/themes/) for a folder named 'mandala', 'trx_mandala', or similar ThemeREX Mandala theme directory. Check theme style.css header or theme functions.php for the theme name and version declaration.
    Affected if ThemeREX Mandala theme files are found on the server
  2. Locate the vulnerable file inclusion code
    Search theme PHP files for include(), require(), include_once(), or require_once() statements that use variables or parameters without proper sanitization. Look for patterns like 'include($_GET[...])' or 'require($param)' in files within the theme directory.
    Affected if Unsanitized include/require calls that accept user-controlled input are found in theme files
  3. Identify the vulnerable parameter
    Examine the identified include/require calls to determine which $_GET, $_POST, or other input parameters control the file path being included. Common parameter names may include 'file', 'path', 'page', 'template', 'load', or similar.
    Affected if A GET/POST parameter directly controls the file path in an include/require statement without validation
  4. Test for directory traversal vulnerability
    If a parameter is identified, verify if the application allows directory traversal by attempting to include a file outside the theme directory, such as ../../../../../../etc/passwd or ../../wp-config.php (do this only in authorized testing environments).
    Affected if The application allows inclusion of files outside the intended theme directory via manipulated path parameters
  5. Check for basename() or input validation
    Review the code around the include/require statements to determine if basename(), realpath(), or any input validation/whitelisting is applied to the parameter before use.
    Affected if No basename(), realpath(), or validation is applied before the file inclusion, leaving the path controllable by attackers

If ThemeREX Mandala theme is installed and contains include/require statements that use unsanitized user input to control file paths without basename() validation, the environment is affected by this LFI vulnerability.
