文件上传处理程序会将已认证客户端的浏览器重定向到直接取自该请求 头的URL，且未将其与应用程序自身的源（origin）进行校验。这使得已认证的攻击者能够构造一个请求，从而在另一个用户完成上传后，其浏览器会被重定向到任意外部目的地。

Source: CVE Program / CVE List V5
Vulnerability Description
A file-upload handler redirects the authenticated client's browser to a URL taken directly from that same request's Referer header, without validating it against the application's own origin. This allows an authenticated attacker to craft a request that causes another user's browser to be redirected to an arbitrary external destination after completing an upload.
