CVE-2024-37300 Information

Description

OAuthenticator is software that allows OAuth2 identity providers to be plugged in and used with JupyterHub. JupyterHub < 5.0 when used with GlobusOAuthenticator could be configured to allow all users from a particular institution only. This worked fine prior to JupyterHub 5.0 because allow_all did not take precedence over identity_provider. Since JupyterHub 5.0 allow_all does take precedence over identity_provider. On a hub with the same config now all users will be allowed to login regardless of identity_provider. identity_provider will basically be ignored. This is a documented change in JupyterHub 5.0 but is likely to catch many users by surprise. OAuthenticator 16.3.1 fixes the issue with JupyterHub 5.0 and does not affect previous versions. As a workaround do not upgrade to JupyterHub 5.0 when using GlobusOAuthenticator in the prior configuration.
