Unknown · Jupyterhub · CVE-2020-36191
Name of the Vulnerable Software and Affected Versions:
JupyterHub version 1.1.0
Description:
The issue allows for CSRF in the admin panel via a request that lacks an ` xsrf` field. This can be demonstrated by a "/hub/api/user" request, which can be used to add or remove a user account.
Recommendations:
For JupyterHub version 1.1.0, consider disabling the `/hub/api/user` endpoint until a patch is available to prevent exploitation. As a temporary workaround, ensure that all requests to the admin panel include a valid ` xsrf` field to mitigate the risk of CSRF attacks.
