CVE-2026-39613
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 kutethemes Boutique kute-boutique allows PHP Local File Inclusion.This issue affects Boutique: from n/a through <= 2.3.3.
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 vulnerability is a PHP Local File Inclusion (LFI) issue in the Boutique theme by kutethemes (versions up to 2.3.3). The application fails to properly validate user-supplied input used in PHP include/require statements, allowing attackers to read sensitive files from the server filesystem by manipulating the input parameter.

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 the Boutique theme and identify its versionCheck the theme's version file (typically version.php, theme.info, or composer.json in the theme directory under wp-content/themes/ or similar). Compare the version number to the affected range (2.3.3 and below).Affected if The installed version is 2.3.3 or any earlier version of the Boutique theme by kutethemes.
-
Identify PHP files using include/require with dynamic parametersSearch the theme directory for PHP files containing include, include_once, require, or require_once statements where the path argument contains variables (e.g., include($file), require($_GET['page']). Look for patterns where user-supplied input could control the file path.Affected if Dynamic file inclusion code exists that uses unsanitized request parameters or variables as file paths.
-
Verify the vulnerable parameter is web-accessibleDetermine if the file inclusion code can be reached via HTTP request (check the surrounding code for how the parameter is passed). Test by making a benign request with a controlled file path (e.g., ?file=../../../../etc/passwd) if the parameter is exposed.Affected if The file inclusion parameter is directly accessible via URL parameters without authentication or validation.
-
Check for sensitive file access via the vulnerabilityIf the vulnerable endpoint is identified, attempt to read a known local file using path traversal (e.g., ../../../../../../../../etc/passwd or ../../wp-config.php) with the affected parameter, observing the server response.Affected if The server returns the contents of files outside the intended directory when path traversal sequences are used in the vulnerable parameter.
You are affected if the Boutique theme version is 2.3.3 or below AND the vulnerable file inclusion code with an exposed parameter is present and accessible in your environment.

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 whitelist-based filtering for all parameters used in include/require statements. Disable allow_url_include in PHP configuration and use basename() or realpath() to sanitize file paths.
