Happy SCSS Compiler - Compile SCSS to CSS automatically <= 1.3.10 - Missing Authorization to Authenticated (Subscriber+) Stored Cross-Site Scripting

The SCSS Happy Compiler – Compile SCSS to CSS & Automatic Enqueue plugin for WordPress is vulnerable to Stored Cross-Site Scripting due to a missing capability check and insufficient sanitization on the import_settings() function in all versions up to, and including, 1.3.10. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject malicious web scripts.
