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 stored Cross-site Scripting (XSS) vulnerability exists in The Plus Addons for Elementor Page Builder Lite plugin versions up to 5.4.2. The vulnerability allows attackers to inject malicious JavaScript code through unsanitized user input that gets rendered in web pages, potentially leading to session hijacking or credential theft when administrators view the affected content.

MitigationUpdate The Plus Addons for Elementor Page Builder Lite to the latest version once available, which should include proper input sanitization and output encoding for all user-supplied data. If no update exists, identify the vulnerable component and implement context-appropriate output escaping.

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

  1. Verify plugin installation
    Navigate to WordPress admin dashboard > Plugins > Installed Plugins and locate 'The Plus Addons for Elementor' in the list. Alternatively, check the /wp-content/plugins/the-plus-addons-for-elementor directory exists on the server.
    Affected if The plugin is installed and active on the WordPress site.
  2. Check installed version
    In the WordPress plugins list, find the version number displayed under the plugin name, or inspect the main plugin file (the-plus-addons-for-elementor.php) and look for the 'Version' header comment.
    Affected if The installed version is lower than 5.5.0 (e.g., 5.4.2, 5.4.1, 5.4.0, etc.).
  3. Identify user input widgets in use
    Review pages and posts built with Elementor that use The Plus Addons widgets. Check each widget that accepts user-submitted content (such as forms, input fields, custom content blocks, or dynamic content display widgets).
    Affected if Any page or post contains a The Plus Addons widget that accepts and displays user input without requiring authentication.
  4. Inspect stored content for malicious scripts
    Query the WordPress database (wp_posts table) for script tags or JavaScript event handlers in content associated with Elementor-built pages. Use SQL: SELECT * FROM wp_posts WHERE post_content LIKE '%<script%' OR post_content LIKE '%onload=%' OR post_content LIKE '%onerror=%'.
    Affected if Any stored content contains unsanitized script tags, javascript: URIs, or event handler attributes (onclick, onerror, onload, etc.).

A site is affected if The Plus Addons for Elementor is installed with a version below 5.5.0 AND any page using the plugin accepts and displays unsanitized user input that could contain malicious scripts.
