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 ApusWP Kossy - Minimalist eCommerce WordPress Theme kossy allows PHP Local File Inclusion.This issue affects Kossy - Minimalist eCommerce WordPress Theme: from n/a through <= 1.45.

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 Kossy WordPress theme contains a PHP Local File Inclusion (LFI) vulnerability caused by improper control of filenames in include/require statements. Attackers can potentially include arbitrary local PHP files by manipulating input parameters, potentially leading to remote code execution if combined with file upload or other attack vectors.

MitigationUpdate the Kossy theme to the latest patched version provided by ApusWP. If no patch is available, audit the theme code for insecure file inclusion patterns and implement proper input validation/sanitization on all include/require statements.

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. Confirm Kossy theme is installed
    Navigate to WordPress dashboard > Appearance > Themes, or check /wp-content/themes/ directory for the kossy folder
    Affected if The Kossy theme is active or installed on the WordPress site
  2. Identify installed Kossy version
    Check the style.css file in /wp-content/themes/kossy/ for the 'Version:' header, or view theme details in WordPress admin under Appearance > Themes
    Affected if Version is not known or cannot be verified against a patched version
  3. Locate vulnerable include/require patterns
    Search theme files for include/require statements using dynamic variables: grep -r 'include.*\$_' or 'require.*\$_' in /wp-content/themes/kossy/ directory
    Affected if Code contains include/require statements directly using user-supplied input without sanitization
  4. Identify affected input parameters
    Review PHP files that use $_GET, $_POST, or $_REQUEST variables in include/require paths; common patterns include '?file=', '?page=', '?template=' in URL parameters
    Affected if URL parameters are used in file inclusion without validation
  5. Check for writable directories accessible via LFI
    Examine if directories like /wp-content/uploads/, /wp-content/cache/, or /tmp/ contain writable files that could be included
    Affected if Attackers could potentially include malicious files from writable directories combined with other vulnerabilities

You are affected if the Kossy theme is installed and contains dynamic file inclusion patterns using unsanitized user input that could allow arbitrary file access.
