Description
The Elementor Website Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG icon control settings in all versions up to, and including, 4.3.5, due to the plugin saving the client-supplied SVG URL of icon controls as-is instead of rebuilding it from a verified SVG attachment. The editor then fetches that URL and inserts the response into the page without sanitizing it. This makes it possible for authenticated attackers, with contributor-level access and above, to point an icon at an attacker-controlled SVG file that runs arbitrary scripts when another user, such as an administrator, opens the affected page in the Elementor editor.
