워드프레스 결제 심플페이 – 우커머스 결제 플러그인 < 5.2.3 - Reflected Cross-Site Scripting via add_query_arg Function

Description

The 워드프레스 결제 심플페이 – 우커머스 결제 플러그인 plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg() function without appropriate escaping on the URL in all versions up to, and including, 5.2.2. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
