CVE-2026-22389
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 Cocco cocco allows PHP Local File Inclusion.This issue affects Cocco: from n/a through <= 2.0.
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 Mikado-Themes Cocco theme (version <= 2.0) contains a PHP Local File Inclusion (LFI) vulnerability due to improper control of filename parameters in include/require statements. An attacker could potentially include malicious files by manipulating the filename parameter, 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.
-
Locate Cocco theme filesSearch the web server document root for the 'cocco' theme directory, typically found in wp-content/themes/cocco or themes/coccoAffected if The Cocco theme directory exists on the server
-
Identify theme versionOpen the style.css file in the theme directory and look for the 'Version:' header in the theme comments, or check version.php if presentAffected if The version listed is 2.0 or lower (including unversioned installs)
-
Find vulnerable file inclusion codeSearch PHP files in the theme for include(), require(), include_once(), or require_once() statements where the path uses variables without validation, for example: include($some_variable) or include($_GET['parameter'])Affected if Unvalidated file inclusion calls using request parameters or variables are found in theme PHP files
-
Check web accessibility of vulnerable parametersIf the vulnerable code uses GET/POST parameters, attempt to access the affected PHP file directly via HTTP and test whether the parameter can be manipulated to include arbitrary filesAffected if The vulnerable file inclusion endpoint is accessible via web and accepts user-controlled parameters without validation
The environment is affected if the Cocco theme version is 2.0 or lower AND vulnerable unvalidated include/require statements using user input are present and accessible via web requests.

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 input validation and sanitization on all file inclusion parameters; use allowlists for permitted files and avoid user-supplied input in include/require statements.
