SCA: security update for oauthenticator (GHSA-r7v4-jwx9-wx43)

medium Tenable Self-Hosted Container Security Plugin ID 418578

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - OAuthenticator is an OAuth token library for the JupyerHub login handler. CILogonOAuthenticator is
 provided by the OAuthenticator package, and lets users log in to a JupyterHub via CILogon. This is
 primarily used to restrict a JupyterHub only to users of a given institute. The allowed_idps configuration
 trait of CILogonOAuthenticator is documented to be a list of domains that indicate the institutions whose
 users are authorized to access this JupyterHub. This authorization is validated by ensuring that the
 *email* field provided to us by CILogon has a *domain* that matches one of the domains listed in
 `allowed_idps`.If `allowed_idps` contains `berkeley.edu`, you might expect only users with valid current
 credentials provided by University of California, Berkeley to be able to access the JupyterHub. However,
 CILogonOAuthenticator does *not* verify which provider is used by the user to login, only the email
 address provided. So a user can login with a GitHub account that has email set to
 `<something>@berkeley.edu`, and that will be treated exactly the same as someone logging in using the UC
 Berkeley official Identity Provider. The patch fixing this issue makes a *breaking change* in how
 `allowed_idps` is interpreted. It's no longer a list of domains, but configuration representing the
 `EntityID` of the IdPs that are allowed, picked from the [list maintained by
 CILogon](https://cilogon.org/idplist/). Users are advised to upgrade. (CVE-2022-31027)
