What it is

The Elementor Website Builder WordPress plugin before 4.3.5 does not sanitize uploaded SVG files on every upload route, allowing users with the Author role and above to upload a file containing JavaScript, which will run in the browser of any user who opens it. Exploitation requires unfiltered file uploads to be enabled in the Elementor Website Builder WordPress plugin before 4.3.5 settings, which is not the default.
