CVE-2026-22436
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 Elated-Themes Helvig helvig allows PHP Local File Inclusion.This issue affects Helvig: from n/a through <= 1.0.
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 confidenceThe Helvig theme by Elated-Themes contains a PHP Local File Inclusion (LFI) vulnerability where the application improperly controls filenames used in include/require statements. An attacker can exploit this to include arbitrary PHP files from the local server, potentially leading to code execution.

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.
-
Confirm Helvig theme installationLocate the Helvig theme directory in the WordPress themes folder (wp-content/themes/helvig) or check the theme's style.css header for 'Helvig' by 'Elated-Themes'Affected if The Helvig theme by Elated-Themes is installed on the WordPress site
-
Identify theme versionOpen the theme's style.css or functions.php file and locate the version declaration in the theme header comment; compare against any available patched version from the vendorAffected if The installed version is older than the patched version provided by Elated-Themes or if no patched version is publicly documented
-
Search for unsafe file inclusion patternsGrep the theme's PHP files (especially template files and includes) for dynamic include/require statements using variable inputs, such as include($_GET[...]) or require($_REQUEST[...]) without sanitizationAffected if Any PHP file in the theme uses include, require, include_once, or require_once with unsanitized user-supplied input from $_GET, $_POST, or $_REQUEST parameters
-
Check for vulnerable file parameter usageReview the identified inclusion code to determine if a parameter (e.g., 'file', 'template', 'page') passed via URL can be manipulated to traverse directories or inject pathsAffected if The application uses a request parameter to determine which file to include without validating that the parameter value corresponds to an allowed, expected file path
-
Verify PHP configuration settingsCheck the PHP configuration file (php.ini) for the allow_url_include directive; if enabled, remote file inclusion becomes possible in addition to local file inclusionAffected if allow_url_include is set to On in php.ini, which would allow inclusion of remote files in conjunction with this vulnerability
If Helvig theme is installed, contains dynamic file inclusion code using unsanitized user input, and the vulnerable parameter can be manipulated to include arbitrary local PHP files, the environment is affected by this LFI vulnerability.
Generated from the published advisory. Verify against your own configuration.
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 dataUpdate Helvig theme to a patched version if available; otherwise implement strict input validation on all file inclusion parameters and ensure allow_url_include is disabled in PHP configuration.
