ElementsKit Elementor Addons and Templates < 3.8.0 - Contributor+ Stored XSS via Simple Tab Widget

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the 'ekit_tab_title' parameter in the Simple Tab widget due to insufficient input sanitization and output escaping on user supplied attributes. 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.
