Summary
In OpenStack Glance through 32.0.0, the /v2/tasks API accepts type=import tasks that
bypass import_filtering_opts, allowing an admin to fetch internal
URLs from the Glance service network (aka SSRF), as long as https:// or http:// is used. This API has been available only to admins since Xena, and it has been deprecated for several releases.
