CVE-2026-22405
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 Overton overton allows PHP Local File Inclusion.This issue affects Overton: from n/a through <= 1.3.
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 Overton theme (version 1.3 and below) contains a PHP Local File Inclusion (LFI) vulnerability where user-supplied input is improperly validated before being used in include/require statements. This allows attackers to read sensitive local files or potentially achieve remote code execution depending on server configuration.

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 Overton theme versionLocate the theme's style.css file (typically in /wp-content/themes/overton/) and check the 'Version:' header in the file comment at the top. Alternatively, look for a version.php file in the theme directory.Affected if The version listed is 1.3 or lower, or no version is displayed (indicating an older unpatched release).
-
Locate PHP files with file inclusion logicSearch the theme directory for PHP files containing 'include', 'require', 'include_once', or 'require_once' statements. Use a command like: grep -r 'include\|require' /path/to/wp-content/themes/overton/*.phpAffected if Any PHP files in the theme contain include/require statements that use variables without hardcoded paths.
-
Inspect file inclusion code for user input handlingExamine the files found in the previous step. Look for patterns where $_GET, $_POST, or $_REQUEST parameters are used directly in include/require statements without sanitization. Example vulnerable pattern: include($_GET['file']);Affected if User-controlled parameters (from GET/POST requests) are passed directly to include/require statements without validation, path restriction, or sanitization functions.
-
Verify the vulnerable endpoint is accessibleIf the vulnerable code is found, identify which URL parameter triggers it (e.g., ?file= or ?template=). Attempt to access the affected page and confirm the parameter is accepted and processed by the theme.Affected if The parameter controlling the file inclusion is accessible via URL and the theme processes it without validation.
If the Overton theme version is 1.3 or below AND PHP code exists that uses unsanitized user input in include/require statements AND that functionality is accessible, the environment is affected by this LFI vulnerability.

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 Overton theme that properly validates and sanitizes input before use in include/require statements, or implement input validation at the application layer to restrict file inclusion to allowed paths.
