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.
A privileged administrator could exploit a vulnerability in the `/v2/tasks` API by crafting a specific import task. This action bypasses security filtering, enabling the administrator to perform Server-Side Request Forgery (SSRF).
As a result, an attacker could access and retrieve sensitive information from internal URLs within the Glance service network. Red Hat severity: Low — CVSS 2.2 (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N).
Weakness: CWE-918. Red Hat lists Red Hat OpenStack Platform 16.2; Red Hat OpenStack Platform 18.0 as not affected.
