CVE-2026-22457
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 Wanderland wanderland allows PHP Local File Inclusion.This issue affects Wanderland: from n/a through <= 1.5.
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 confidenceLocal File Inclusion (LFI) vulnerability in the Mikado-Themes Wanderland theme (version <= 1.5) allows attackers to include arbitrary local PHP files due to improper control of filenames in include/require statements. This can lead to sensitive file disclosure and potentially remote code execution if attacker-controlled files exist on the server.

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 Wanderland theme installationSearch for the wanderland theme directory in your web root, typically found at /wp-content/themes/wanderland/ for WordPress installationsAffected if The wanderland theme directory exists on the server
-
Identify installed theme versionOpen the style.css file in the theme root directory and locate the 'Version:' header in the theme comments at the top of the fileAffected if The version listed is 1.5 or lower, or if no version is specified but the theme is present
-
Examine PHP files for include/require with user inputSearch theme PHP files (particularly in includes/ or similar directories) for patterns like 'include(', 'require(', 'include_once(', 'require_once(' combined with '$_GET', '$_POST', '$_REQUEST', or '$_COOKIE' variablesAffected if Any include/require statement uses unsanitized user-supplied parameters from $_GET, $_POST, $_REQUEST, or $_COOKIE arrays
-
Identify the vulnerable file inclusion parameterReview the identified include/require statements to determine which specific query parameter (e.g., 'file', 'page', 'template', 'path') controls the included file pathAffected if A parameter controllable via URL query string (GET) or POST data is used directly in file inclusion functions without validation
-
Test if the LFI is exploitableAttempt to include a known file using the identified parameter (e.g., ?param=../../../../../../etc/passwd or ?param=../wp-config.php), observing whether the file contents are returnedAffected if The server returns contents of files outside the theme directory based on the parameter value
A user is affected if the Wanderland theme version is 1.5 or lower AND the theme contains PHP files with include/require statements that use unsanitized user input from request 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 Wanderland theme if available. If no patch exists, implement strict whitelist-based input validation on all file inclusion parameters and avoid using user input directly in include/require statements.
