Is HT Contact Form safe? Known vulnerabilities and latest version

The HT Contact Form – Drag & Drop Form Builder for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Rich Text Editor Field in all versions up to, and including, 2.10.2 due to insufficient input sanitization and output escaping.
