Description

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.

Affected products

OpenStack Glance: from 30.0.0 before 30.3.0; from 31.0.0 before 31.1.1; 32.0.0 — fixed in 30.3.0, 31.1.1

How to fix

Upgrade to a fixed version: OpenStack Glance 30.3.0, 31.1.1. Check the vendor advisory for mitigations.
