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 checksWork through these to decide whether this CVE applies to you.
-
Locate the installed version of ElementInvader Addons for ElementorCheck the WordPress plugin admin panel under Plugins, or inspect the plugin header in the main plugin file (typically in wp-content/plugins/elementinvader-addons-for-elementor/) for the Version fieldAffected if The installed version is lower than 1.4.4 (e.g., 1.4.3, 1.4.2, earlier versions)
-
Identify widgets or modules that accept user inputReview all active ElementInvader widgets in the Elementor editor. Look for any text input fields, form fields, or content fields where you can enter custom text that gets displayed on the frontendAffected if Any ElementInvader widget that accepts user-supplied text and renders it directly to the page without visible encoding is in use
-
Test for unsanitized DOM renderingInsert a test script tag such as <script>alert('test')</script> into any ElementInvader user input field, publish the page, and view the rendered HTML source to see if the tag appears unencodedAffected if The script tag executes as JavaScript or appears in the page source without HTML encoding (e.g., shows as <script> rather than <script>)
-
Inspect browser developer console for DOM XSS patternsLoad a page using ElementInvader widgets with user input, open the browser console, and check the Elements panel to see if user input appears as raw HTML rather than text contentAffected if User input is inserted as innerHTML or similar DOM manipulation rather than as textContent or properly escaped
You are affected if ElementInvader Addons for Elementor is installed below version 1.4.4 and any widget accepts user input that renders directly into the DOM without HTML encoding.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to a patched version of ElementInvader Addons for Elementor (version 1.4.4 or later). If no patch is available, implement Content Security Policy (CSP) headers and validate/sanitize all user inputs before DOM insertion.
