CVE-2026-77648

Quick assessment

Affected
OpenStack Glance
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 OpenStack Glance 32.0.0 及更早版本中，/v2/tasks API 接受 type=import 类型的任务，这些任务会绕过 import_filtering_opts 配置选项，使得管理员能够通过 Glance 服务网络（即 SSRF，服务器端请求伪造）获取内部 URL，前提是使用的是 https:// 或 http:// 协议。该 API 自 Xena 版本起仅对管理员开放，并且已在多个版本中被标记为弃用。

Vulnerability 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.
