CVE-2026-22403
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 Mikado-Themes Innovio innovio allows PHP Local File Inclusion.This issue affects Innovio: from n/a through <= 1.9.
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 · high confidenceA PHP Local File Inclusion vulnerability exists in the Mikado-Themes Innovio theme (version <= 1.9) where user-supplied input is improperly used in include/require statements without sufficient validation, potentially allowing attackers to include arbitrary local files or execute malicious PHP code.

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 Innovio theme is installedLocate the theme directory. Common paths: wp-content/themes/innovio/ (WordPress) or the theme folder in the respective CMS. Check for the existence of style.css or theme config files containing 'Innvio' or 'Mikado Themes'.Affected if The Innovio theme by Mikado Themes is present on the server.
-
Determine the installed theme versionOpen the main theme file (typically style.css, functions.php, or a version.php file) and look for a version declaration comment or variable. Compare the version number to 1.9.Affected if The theme version is 1.9 or lower.
-
Identify PHP files using dynamic includesSearch the theme directory for PHP files containing include, require, include_once, or require_once statements with variables or parameters (e.g., include($some_var), require($_GET['page']). Use grep or a code search tool to find patterns like 'include($' or 'require($_' within the theme folder.Affected if Dynamic include/require statements using variables or user-supplied input are found in theme PHP files.
-
Inspect parameters used in file inclusion operationsReview the identified include/require files. Trace the source of variables used in these statements. Check if any originate from $_GET, $_POST, or $_REQUEST superglobals without proper sanitization or validation.Affected if Parameters passed to include/require are derived from user input without validation.
-
Test for LFI vulnerability (if authorized and safe)If you have authorization, use a low-impact test: attempt to include a known local file (e.g., ../../../../etc/passwd or the theme's own config file) via a suspected vulnerable parameter in a request to the site. Observe whether the file contents are reflected in the response.Affected if Arbitrary local files can be included and their contents revealed through URL parameters.
The environment is affected if the Innovio theme version is 1.9 or lower AND the theme contains PHP files with include/require statements that use unsanitized user input parameters.

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 dataUpgrade to a patched version of the Innovio theme. If immediate patching is unavailable, implement strict input validation on all parameters used in file inclusion operations and disable allow_url_fopen/allow_url_include in PHP configuration.
