How to fix?

Upgrade oauthenticator to version 16.3.1 or higher.

Overview

Affected versions of this package are vulnerable to Incorrect Authorization due to allow_all taking precedence over identity_provider. On a hub with the same config, now all users will be allowed to login, regardless of identity_provider, which will basically be ignored.

Note: This vulnerability is introduced since JupyterHub v5.0.

Workaround

Do not upgrade to JupyterHub 5.0 when using GlobusOAuthenticator in the prior configuration.
