Description Vasyl Kaigorodov 2015-07-16 12:56:11 UTC

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>
