Description

In OpenStack Glance before 32.0.1, the location API does not validate destination hosts when adding an HTTP location to an image. Unlike the web-download import path, the location API only checks the URL scheme and does not apply the import_filtering_opts host restrictions. An authenticated user can add a location pointing to internal endpoints such as the cloud metadata service (169.254.169.254), and retrieve the response by downloading the image data. This affects both the new POST /v2/images/{id}/locations API and the old PATCH API when show_multiple_locations is enabled. Deployments with the HTTP store backend enabled are affected.

Affected products

OpenStack Glance: from 16.0.0 before 30.2.1; from 31.0.0 before 31.1.1; from 32.0.0 before 32.0.1 — fixed in 30.2.1, 31.1.1, 32.0.1

How to fix

Upgrade to a fixed version: OpenStack Glance 30.2.1, 31.1.1, 32.0.1. Check the vendor advisory for mitigations.
