Gum Elementor Addon <= 1.3.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via Post Meta Widget

The Gum Elementor Addon plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Post Meta widget in all versions up to, and including, 1.3.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
