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 confidence

Stored Cross-site Scripting (XSS) vulnerability in the Author Box WP Lens (author-box-for-divi) WordPress plugin allows authenticated or anonymous users to inject malicious JavaScript code through author box input fields. The malicious payload is stored in the database and executed when other users view pages displaying the affected author box, potentially leading to session hijacking, credential theft, or defacement.

MitigationUpdate to a patched version of Author Box WP Lens if available; otherwise, disable the plugin until a fix can be applied. Implement proper input sanitization and output encoding on all author box fields before storing and displaying user-supplied data.

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. Verify the Author Box WP Lens plugin is installed
    Navigate to WordPress Admin > Plugins and look for 'Author Box WP Lens' or 'author-box-for-divi' in the installed plugins list. Note whether the plugin is active or inactive.
    Affected if The plugin is installed and active on the WordPress site.
  2. Determine the installed plugin version
    Click on the plugin in the WordPress plugins list to view its details, or inspect the plugin files in wp-content/plugins/author-box-for-divi/ for a version number in the main PHP file or readme.txt.
    Affected if The installed version cannot be compared to a patched version because none is provided in the CVE data.
  3. Confirm author box functionality is enabled
    Check the plugin settings under Divi Theme Options or the plugin settings page to see if any author box modules or layouts are enabled and assigned to display on pages or posts.
    Affected if Author box modules are configured and rendering on site pages.
  4. Inspect author data in the database for XSS payloads
    Query the WordPress database tables (typically wp_usermeta or custom plugin tables) for author box-related meta fields. Look for script tags, javascript:, onload, or other XSS patterns in stored values.
    Affected if Malicious JavaScript payloads are present in author-related database fields.
  5. Examine page source for executed XSS
    View the HTML source of pages displaying author boxes. Search for unsanitized script tags, event handlers, or suspicious inline JavaScript that originates from author input fields.
    Affected if Unencoded XSS payloads are rendering in the browser when viewing author boxes.

The site is affected if the Author Box WP Lens plugin is active with author boxes configured, and malicious scripts are stored in author data or executing in page output.
