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 Daiquiri daiquiri allows PHP Local File Inclusion.This issue affects Daiquiri: from n/a through <= 1.2.4.

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 (LFI) vulnerability in ThemeREX Daiquiri <= 1.2.4 allows attackers to include arbitrary files from the server filesystem via improperly controlled filename parameters in PHP include/require statements. This can lead to sensitive file disclosure (e.g., configuration files, credentials) and potentially remote code execution.

MitigationImplement strict input validation and whitelist-based allowlisting for file inclusion paths; disable allow_url_include in PHP configuration; ensure all user-supplied filename parameters are validated against an allowed file list and cannot traverse outside intended directories.

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 Daiquiri is installed
    Check your WordPress or PHP application for the ThemeREX Daiquiri theme or plugin by examining the theme/plugin directory or checking the installed components list.
    Affected if ThemeREX Daiquiri is present in your environment
  2. Determine the installed version
    Locate the version information for ThemeREX Daiquiri (typically in a version.php, style.css header, or plugin readme file within the theme/plugin directory) and compare it to the affected range of 1.2.4 and below.
    Affected if The installed version is 1.2.4 or any earlier version
  3. Locate the vulnerable file inclusion code
    Search the ThemeREX Daiquiri source files for PHP include, include_once, require, or require_once statements that use filename parameters derived from user input (such as $_GET, $_POST, or similar superglobals).
    Affected if User-controllable parameters are used in include/require statements without proper sanitization
  4. Verify the vulnerable parameter is accessible
    Check if the affected PHP scripts containing the insecure file inclusion are directly accessible via HTTP requests (not restricted by authentication, referrer checks, or other access controls).
    Affected if The vulnerable scripts can be accessed without sufficient access restrictions
  5. Check for signs of exploitation
    Review web server access logs for unusual patterns such as directory traversal sequences (e.g., ../../) in query parameters targeting the affected scripts, or examine application logs for repeated file inclusion attempts.
    Affected if Log evidence shows directory traversal attempts or unauthorized file access via the vulnerable parameter

Your environment is affected if ThemeREX Daiquiri version 1.2.4 or lower is installed and the vulnerable file inclusion parameter is accessible without proper validation.

Mitigation

Implement strict input validation and whitelist-based allowlisting for file inclusion paths; disable allow_url_include in PHP configuration; ensure all user-supplied filename parameters are validated against an allowed file list and cannot traverse outside intended directories.
