CVE-2024-37300

Impact

### Impact JupyterHub < 5.0, when used with `GlobusOAuthenticator`, could be configured to allow all users from a particular institution only. The configuration for this would look like: ```python # Require users to be using the "foo.horse" identity provider, often an institution or university c.GlobusAuthenticator.identity_provider = "foo.horse" # Allow everyone who has that identity provider to log in c.GlobusAuthenticator.allow_all = True ``` 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](https://jupyterhub.readthedocs.io/en/stable/howto/upgrading-v5.html#authenticator-allow-all-and-allow-existing-users) in JupyterHub 5.0, but is likely to catch many users by surprise. ### Patches OAuthenticator 16.3.1 fixes the issue with JupyterHub 5.0, and does not affect previous versions. ### Workarounds Do not upgrade to JupyterHub 5.0 when using `GlobusOAuthenticator` in the prior configuration.
