CVE-2025-49371
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 AncoraThemes Strux strux allows PHP Local File Inclusion.This issue affects Strux: 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 (LFI) vulnerability exists in AncoraThemes Strux theme where the application does not properly validate user-supplied input used in include/require statements. An attacker could exploit this to read sensitive files from the server's filesystem by manipulating the file path parameters, potentially leading to information disclosure or code execution in certain contexts.

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 if Strux theme is installedCheck the theme directory for AncoraThemes Strux - typically found in wp-content/themes/strux or similar path. Look for theme files like style.css containing 'Strux' or 'AncoraThemes' in the theme metadata.Affected if Strux theme by AncoraThemes is present in the WordPress themes directory
-
Determine the installed version of StruxOpen the theme's style.css file and locate the 'Version:' header in the theme comment block. Compare this version against any available patch information from AncoraThemes.Affected if The installed version has not been patched for the LFI vulnerability
-
Inspect include/require usage in theme filesSearch theme PHP files (particularly those handling templates or shortcodes) for include, require, include_once, or require_once statements that use variables or user input without proper sanitization. Look for patterns like 'include($var)' or 'require($_GET[...])'.Affected if Dynamic file inclusion uses unsanitized input from request parameters or user data
-
Check for vulnerable parameter handlingReview any PHP files that accept input via $_GET, $_POST, or $_REQUEST and pass it directly to include/require statements. Test if the application allows path traversal (e.g., ../../) in such parameters.Affected if URL parameters or form inputs can be used to control which files are included
-
Verify input validation mechanismsExamine the theme's PHP files for functions that validate or sanitize input before use in include/require, such as whitelist checks, basename(), or realpath() validation.Affected if No input validation exists before file inclusion operations
The environment is affected if the AncoraThemes Strux theme is installed and uses dynamic file inclusion with unsanitized user input in include/require statements.

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 using allowlists for permitted files, apply basename() to strip directory traversal sequences, and refactor code to avoid direct use of user input in include/require statements.
