Style Kits – Advanced Theme Styles for Elementor <= 2.5.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Kit Title

The Style Kits – Advanced Theme Styles for Elementor, Elementor Kits & Elementor Patterns plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the '/wp-json/agwp/v1/tokens/save' endpoint kit title parameter in versions up to, and including, 2.5.0 due to insufficient input sanitization and output escaping in an admin attribute context. 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.
