Premium Addons for Elementor <= 4.11.70 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'custom_svg' Parameter

The Premium Addons for Elementor – Powerful Elementor Templates & Widgets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'custom_svg' parameter in versions up to, and including, 4.11.70 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
