CVE-2021-41247: incomplete JupyterHub logout with simultaneous JupyterLab sessions

November 8, 2021 (updated September 24, 2024)

Users of JupyterLab with JupyterHub 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) reinstated after logout, if another active JupyterLab session is open while the logout takes place.
