devel/ipython -- CSRF possible remote execution vulnerability

Kyle Kelley reports:

Summary: POST requests exposed via the IPython REST API are
vulnerable to cross-site request forgery (CSRF). Web pages on
different domains can make non-AJAX POST requests to known IPython
URLs, and IPython will honor them. The user’s browser will
automatically send IPython cookies along with the requests. The
response is blocked by the Same-Origin Policy, but the request
isn’t.
API paths with issues:

POST /api/contents/<path>/<file>
POST /api/contents/<path>/<file>/checkpoints
POST /api/contents/<path>/<file>/checkpoints/<checkpoint_id>
POST /api/kernels
POST /api/kernels/<kernel_id>/<action>
POST /api/sessions
POST /api/clusters/<cluster_id>/<action>
