以下是该漏洞描述的中文翻译： User Frontend WordPress 插件在 4.3.11 版本之前，当用户在前端编辑表单中重新打开已提交的文章时，未能阻止用户提供的字段值被反序列化。这使得具有订阅者（subscriber）权限或更高权限的认证用户能够执行 PHP 对象注入（PHP Object Injection）。如果目标站点上存在合适的“gadget chain”（利用链/小工具链），该漏洞可能导致远程代码执行（RCE）。 --- 术语说明（供参考）： PHP Object Injection: 指攻

WP User Frontend < 4.3.11 - Subscriber+ PHP Object Injection via Frontend Post Edit Form

Vulnerability Description
The User Frontend WordPress plugin before 4.3.11 does not prevent user-supplied field values from being deserialized when a submitted post is reopened in its frontend editing form, allowing authenticated users with subscriber-level access and above to perform PHP Object Injection, which may lead to remote code execution when a suitable gadget chain is present on the site.
