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

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

A reflected XSS vulnerability in the Themebox WordPress theme allows attackers to inject malicious JavaScript through unsanitized user input that gets rendered in the generated web page without proper output encoding.

MitigationImplement proper input validation and output encoding/escaping for all user-supplied data before rendering in HTML context. Use WordPress sanitization functions like esc_html(), esc_attr(), or wp_kses() as appropriate.

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 Themebox theme is installed
    Navigate to WordPress admin > Appearance > Themes and verify the Themebox theme appears in the theme list, or inspect the wp-content/themes/ directory for a themebox folder
    Affected if The Themebox theme folder exists in the WordPress themes directory
  2. Verify theme is active
    In WordPress admin > Appearance > Themes, check if Themebox is the currently active theme (has a 'Active' badge or is being used on the live site)
    Affected if Themebox is set as the active theme on the WordPress site
  3. Identify the installed theme version
    Open wp-content/themes/themebox/style.css and look for the 'Version:' header in the CSS file comment block. Compare this version to any official advisories or release notes for CVE-2025-52747
    Affected if The installed version matches an affected version listed in official vulnerability documentation
  4. Locate reflected user input in theme files
    Search theme PHP files (especially header.php, footer.php, search.php, index.php, and template files) for instances where $_GET, $_POST, or $_REQUEST superglobals are output directly to HTML without sanitization functions like esc_html(), esc_attr(), or esc_url()
    Affected if Theme files contain code that echoes request parameters directly into HTML output without encoding
  5. Test for XSS in URL parameters
    Visit the site with Themebox active and append a test parameter (e.g., ?test=<script>alert(1)</script>) to any page URL. View the page source to see if the script tags appear unencoded in the rendered HTML
    Affected if The injected script tags render literally in the page source without HTML encoding
  6. Check WordPress escaping functions in template files
    Review theme template files for proper use of WordPress escaping functions. Look for esc_html(), esc_attr(), esc_url(), and wp_kses() around any dynamic content that could originate from user input
    Affected if Theme template files lack proper escaping functions around areas that handle user-supplied data

You are affected if the Themebox theme is active on your WordPress site and contains code that reflects user input without HTML encoding, regardless of version, since the core vulnerability is unsanitized output rendering.
