JupyterLab vulnerable to potential authentication and CSRF tokens leak

Details

### Impact Users of JupyterLab who click on a malicious link may get their `Authorization` and `XSRFToken` tokens exposed to a third party when running an older `jupyter-server` version.

### Patches JupyterLab 4.1.0b2, 4.0.11, and 3.6.7 were patched.

### Workarounds No workaround has been identified, however users should ensure to upgrade `jupyter-server` to version 2.7.2 or newer which includes a redirect vulnerability fix.
