Overview

jupyterhub is a JupyterHub: A multi-user server for Jupyter notebooks

Affected versions of this package are vulnerable to Information Exposure. Users who have multiple JupyterLab tabs open in the same browser session, may see incomplete logout from the single-user server, as fresh credentials (for the single-user server only, not the Hub) are reinstated after logout if another active JupyterLab session is open while the logout takes place.
