Input validation vulnerability in 아임포트 결제버튼 생성 플러그인 1.1.19

A popular plugin used for creating payment buttons on WordPress websites, called “아임포트 결제버튼 생성 플러그인 plugin,” has a security vulnerability that allows attackers to inject harmful code onto web pages. This can occur when the plugin is used on versions up to 1.1.19, as it does not properly sanitize and escape user input. This means that even authenticated attackers with contributor-level access or higher can insert malicious scripts onto pages, which will then be executed whenever a user visits the affected page.
