우커머스 네이버페이 <= 3.3.7 - Authenticated (Contributor+) Stored Cross-Site Scripting via mnp_purchase Shortcode

The 우커머스 네이버페이 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's mnp_purchase shortcode in all versions up to, and including, 3.3.7 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.
