CVE-2026-71198: Openstack Glance

High severity, CVSS 7.0. EPSS: 0.5% chance of exploitation in the next 30 days.

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 (fixed in 30.2.1); from 31.0.0, before 31.1.1 (fixed in 31.1.1); from 32.0.0, before 32.0.1 (fixed in 32.0.1)
