Hustle WordPress 插件 7.8.14.2 之前版本存在漏洞：当插件将表单提交值替换到提交后返回的消息中时，未能防止其中的短代码（shortcodes）被执行。原因是插件所应用的保护机制可以通过嵌套（nesting）方式被绕过，这使得未认证用户能够执行网站上已注册的任何短代码。

Vulnerability Title
Hustle < 7.8.14.2 - Unauthenticated Arbitrary Shortcode Execution via Success Message Placeholders
Source: CVE Program / CVE List V5
Vulnerability Description
The Hustle WordPress plugin before 7.8.14.2 does not prevent shortcodes in submitted form values from being executed when it substitutes those values into the message it returns after submission, because the guard it applies can be defeated by nesting, allowing unauthenticated users to run any shortcode registered on the site.
