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.

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.

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. Locate the Boutique theme installation
    Find the kute-boutique theme files in your Shopify theme directory, WordPress wp-content/themes folder, or relevant CMS theme location. Common paths include /themes/kute-boutique or similar. Identify the main style.css or theme.json file containing the theme version metadata.
    Affected if The kute-boutique theme folder exists in your environment
  2. Determine the installed Boutique theme version
    Open the theme's style.css file (usually in the theme root) and locate the Version or Version: header in the file comment block. Alternatively, check package.json if present for a "version" field.
    Affected if The version number found is lower than 2.4.6 (for example, 2.4.5, 2.4.0, 2.3.x, etc.)
  3. Identify user-controlled input points in the theme
    Search theme template files (.php, .liquid, .twig, .html) for dynamic parameters that reflect user input back to the page, such as query parameters, form inputs, or URL segments. Look for code using $_GET, $_REQUEST, or URL variables without sanitization functions like htmlspecialchars or esc_html.
    Affected if The theme templates accept and render URL parameters or form data without proper output encoding
  4. Verify if the theme is actively processing user requests
    Check if your web server is actively serving pages using the Boutique theme. Review access logs or server configuration to confirm the theme is loaded when visitors access the site.
    Affected if The Boutique theme is actively loaded and serving pages to users

Your environment is affected if the kute-boutique theme is installed with a version lower than 2.4.6 and the theme processes user-supplied input that gets reflected in web pages without sanitization.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to Boutique version 2.4.6 or later which contains the security fix, or implement proper input validation and output encoding on all user-controlled inputs in the theme.

Recommended fix Moderate confidence

  1. 1. Backup your WordPress site database and files before making any changes
  2. 2. Navigate to Appearance > Themes in your WordPress admin dashboard
  3. 3. Locate the Boutique (kute-boutique) theme
  4. 4. Check for theme updates or manually download version 2.4.6 or later from the theme vendor
  5. 5. Update the theme to the latest available version that includes the security fix
  6. 6. After updating, clear any caching plugins and verify the site functions correctly
  7. 7. Test that the XSS vulnerability is resolved by verifying user input is properly sanitized in affected areas
Caveat Minor/standard - always test updates in staging first as customizations may be affected
