CVE-2024-37300
June 12, 2024
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.
