## Affected

- Unknown King Addons for Elementor: fixed in 51.1.81

## Description

The King Addons for Elementor WordPress plugin before 51.1.81 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.
