Element Pack Elementor Addons and Templates <= 8.1.5 - Authenticated (Contributor+) Stored Cross-Site Scripting via Open Street Map Widget Marker Content

The Element Pack Elementor Addons and Templates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'marker_content' parameter in versions up to, and including, 8.1.5 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.
