King Addons for Elementor < 51.1.81 - Contributor+ Stored XSS via Template Catalog Import

Description

The plugin does not perform an object-level authorization check when importing template content into a page, allowing users with contributor-level access and above to overwrite the Elementor content of arbitrary posts and pages, including those owned by administrators, and to inject JavaScript through a widget setting that is output without escaping, resulting in Stored Cross-Site Scripting that executes in the session of any user who views the affected page.
