The Ultimate Addons for Elementor (Formerly Elementor Header & Footer Builder) plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the savehfecompatibilityoptioncallback ()function in all versions up to, and including, 2.4.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update the compatibility option setting.

The Ultimate Addons for Elementor (Formerly Elementor Header & Footer Builder) WordPress plugin before 2.5.0 does not sanitize SVG file contents when uploaded through the xmlrpc.php endpoint using base64 encode, leading to a Cross-Site Scripting vulnerability.
