Jupyter Server Proxy's Websocket Proxying does not require authentication

Jupyter Server Proxy allows users to run arbitrary external processes alongside their Jupyter notebook servers and provides authenticated web access. Prior to versions 3.2.3 and 4.1.1, Jupyter Server Proxy did not check user authentication appropriately when proxying websockets, allowing unauthenticated access to anyone who had network access to the Jupyter server endpoint. This vulnerability can allow unauthenticated remote access to any websocket endpoint set up to be accessible via Jupyter Server Proxy. In many cases, this leads to remote unauthenticated arbitrary code execution, due to how affected instances use websockets. The websocket endpoints exposed by `jupyter_server` itself is not affected. Projects that do not rely on websockets are also not affected. Versions 3.2.3 and 4.1.1 contain a fix for this issue.

Jupyter Server 安全漏洞

Jupyter Server是Jupyter组织的一款用于为Jupyter Web应用提供后端服务的应用软件。 Jupyter Server Proxy存在安全漏洞，该漏洞源于不会适当检查用户身份验证，从而允许具有网络访问权限的任何人进行未经身份验证的访问。
