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 · unedited
Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in AncoraThemes Inset inset allows PHP Local File Inclusion.This issue affects Inset: from n/a through <= 1.18.0.

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 confidence

The Inset theme by AncoraThemes contains a PHP Local File Inclusion (LFI) vulnerability due to improper control of filenames in include/require statements. Attackers can manipulate input parameters to include arbitrary PHP files from the local server, potentially leading to remote code execution.

MitigationUpgrade to a patched version of the Inset theme that properly validates and sanitizes file path inputs before use in include/require statements, or implement input validation and whitelist controls on the vulnerable code paths.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed Inset theme version
    Locate the theme's style.css file (typically in /wp-content/themes/inset/) and find the 'Version:' declaration in the file header. Alternatively, check the theme version through the WordPress admin appearance section.
    Affected if The version number displayed is 1.18.0 or lower.
  2. Verify the theme is actively loaded
    Confirm the Inset theme is currently active on the WordPress site. Check wp_options table for 'template' or 'stylesheet' option values, or inspect the site's active theme through the WordPress admin dashboard.
    Affected if The Inset theme is the active theme and the version from step 1 is 1.18.0 or lower.
  3. Identify user-controlled file path parameters
    Review PHP files in the theme directory for request parameters (e.g., $_GET, $_POST, $_REQUEST) being used in include(), require(), include_once(), or require_once() statements without proper sanitization. Search for patterns like 'include($_GET[' or 'require($_REQUEST'.
    Affected if Any include/require statements use raw user input from URL or form parameters without validation.
  4. Inspect file inclusion functions for path traversal
    Examine PHP files in the theme for file inclusion functions that accept file paths. Check if parameters allow directory traversal sequences (../) or direct file paths. Look for code that concatenates user input into file paths.
    Affected if The application accepts file path parameters that can be manipulated to access arbitrary local files, particularly PHP files outside the intended directory.

You are affected if the Inset theme version is 1.18.0 or lower and the codebase contains include/require statements that use unsanitized user input to construct file paths.
