Versions of Jupyter Server Proxy prior to 3.2.1 are vulnerable to Server-Side Request Forgery (SSRF). Any user deploying Jupyter Server or Notebook with jupyter-proxy-server extension enabled is affected. A lack of input validation allows authenticated clients to proxy requests to other hosts, bypassing the `allowed_hosts` check.

Versions of 3.x prior to 3.2.4 and 4.x prior to 4.2.0 have a reflected cross-site scripting (XSS) issue. The `/proxy` endpoint accepts a `host` path segment in the format `/proxy/<host>`. When this endpoint is called with an invalid `host` value, `jupyter-server-proxy` replies with a response that includes the value of `host`, without sanitization [2]. A third-party actor can leverage this by sending a phishing link with an invalid `host` value containing custom JavaScript to a user. When the user clicks this phishing link, the browser renders the response of `GET /proxy/<host>`, which runs the custom JavaScript contained in `host` set by the actor. As any arbitrary JavaScript can be run after the user clicks on a phishing link, this issue permits extensive access to the user's JupyterLab instance for an actor. Patches are included in versions 4.2.0 and 3.2.4. As a workaround, server operators who are unable to upgrade can disable the `jupyter-server-proxy` extension.",

Un actor externo puede aprovechar esto enviando un enlace de phishing con un valor de \"host\" no válido que contenga JavaScript personalizado a un usuario. Cuando el usuario hace clic en este enlace de phishing, el navegador muestra la respuesta `GET /proxy/`, que ejecuta el JavaScript personalizado contenido en `host` establecido por el actor. Como se puede ejecutar cualquier JavaScript arbitrario después de que el usuario hace clic en un enlace de phishing, este problema permite un acceso extenso a la instancia de JupyterLab del usuario para un actor.

         value: "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.",

         value: "Jupyter Server Proxy permite a los usuarios ejecutar procesos externos arbitrarios junto con sus servidores portátiles Jupyter y proporciona acceso web autenticado. Antes de las versiones 3.2.3 y 4.1.1, Jupyter Server Proxy no verificaba adecuadamente la autenticación del usuario al utilizar websockets, lo que permitía el acceso no autenticado a cualquier persona que tuviera acceso de red al endpoint del servidor Jupyter. Esta vulnerabilidad puede permitir el acceso remoto no autenticado a cualquier endpoint de websocket configurado para ser accesible a través de Jupyter Server Proxy. En muchos casos, esto conduce a la ejecución remota de código arbitrario no autenticado, debido a cómo las instancias afectadas usan websockets. Los endpoints de websocket expuestos por el propio `jupyter_server` no se ven afectados. Los proyectos que no dependen de websockets tampoco se ven afectados. Las versiones 3.2.3 y 4.1.1 contienen una solución para este problema. ",

               value: "Jupyter Server Proxy allows users to run arbitrary external processes alongside their notebook server and provide authenticated web access to them. Versions of 3.x prior to 3.2.4 and 4.x prior to 4.2.0 have a reflected cross-site scripting (XSS) issue. The `/proxy` endpoint accepts a `host` path segment in the format `/proxy/<host>`. When this endpoint is called with an invalid `host` value, `jupyter-server-proxy` replies with a response that includes the value of `host`, without sanitization [2]. A third-party actor can leverage this by sending a phishing link with an invalid `host` value containing custom JavaScript to a user. When the user clicks this phishing link, the browser renders the response of `GET /proxy/<host>`, which runs the custom JavaScript contained in `host` set by the actor. As any arbitrary JavaScript can be run after the user clicks on a phishing link, this issue permits extensive access to the user's JupyterLab instance for an actor. Patches are included in versions 4.2.0 and 3.2.4. As a workaround, server operators who are unable to upgrade can disable the `jupyter-server-proxy` extension.",

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.",

Versions of Jupyter Server Proxy prior to 3.2.1 are vulnerable to Server-Side Request Forgery (SSRF).
