워드프레스 결제 심플페이 – 우커머스 결제 플러그인 <= 5.1.4 - Authenticated (Contributor+) Stored Cross-Site Scripting pafw_instant_payment Shortcode

The 워드프레스 결제 심플페이 – 우커머스 결제 플러그인 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's pafw_instant_payment shortcode in all versions up to, and including, 5.1.4 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.
