CVE-2026-71198: [OSSA-2026-038] OpenStack Glance: Multiple SSRF vulnerabilities in web-download and HTTP image APIs (CVE-2026-71196, CVE-2026-71197, CVE-2026-71198)

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 importfilteringopts 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 showmultiplelocations is enabled. Deployments with the HTTP store backend enabled are affected.
