CVE-2026-39684
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 · uneditedImproper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in UnTheme OrganicFood organicfood allows PHP Local File Inclusion.This issue affects OrganicFood: from n/a through <= 3.6.4.
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 confidenceA Local File Inclusion (LFI) vulnerability in UnTheme's OrganicFood theme allows attackers to manipulate filename parameters in PHP include/require statements to access sensitive local files. This occurs due to improper validation of user-supplied input before passing it to PHP's include or require functions.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify OrganicFood installationSearch for files containing 'organicfood', 'UnTheme', or theme configuration files in the web root directory (common paths: /wp-content/themes/, /themes/, or application root)Affected if The OrganicFood theme/application by UnTheme is present on the server
-
Locate PHP files with include/require statements using variable pathsSearch PHP source files for patterns like 'include($_GET', 'require($_GET', 'include($', 'require($' where the variable could be controlled via URL parametersAffected if File inclusion functions use variables that could be influenced by user input without proper validation
-
Examine the file path parameter handlingReview the identified include/require statements to determine if URL parameters (e.g., ?file=, ?page=, ?path=) are directly used in the include/require function without sanitizationAffected if URL parameters are directly passed to include/require functions without validation using basename(), realpath(), or allowlists
-
Check for input validation on file parametersInspect the PHP code around the vulnerable inclusion points for validation functions like basename(), realpath(), or whitelist checks before the include/require statementAffected if No input validation is present, or validation does not properly restrict to allowed files/directories only
-
Test for LFI vulnerabilityIf direct code inspection is not possible, attempt to access non-PHP files via suspected parameters (e.g., ../../../../etc/passwd) to confirm the LFI exists; monitor server responses for file contentsAffected if The server returns contents of files outside the intended directory when path parameters are manipulated
The system is affected if the OrganicFood application is installed AND contains PHP code where user-controlled parameters are directly used in include/require statements without validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict whitelist-based input validation for any parameters used in include/require statements, ensuring only allowed files can be included. Use basename() and realpath() to sanitize and validate file paths, avoiding direct user input in file inclusion logic.
