## Description

The WPKoi Templates for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several Elementor widget settings (QR Code width and height, Advanced Heading Circle Type radius and direction, and the Interactive Cursor icon) in all versions up to, and including, 3.7.3. This is due to insufficient input sanitization and output escaping. These values are printed unquoted into inline JavaScript with only attribute escaping, or placed in a data attribute that the front-end script inserts as HTML. 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.
