The Zion Builder WordPress plugin through 3.6.17 does not sanitize uploaded SVG files or validate their contents before storing them in a publicly accessible location and serving them from the site's own origin, allowing authenticated users with the Author role or above to upload a crafted SVG containing JavaScript that executes in the browser of anyone who opens the file.
