CVE-2026-77648Network attack vector

Admin-only SSRF via legacy task import

Published Aug 20, 2026 · Updated Aug 20, 2026

Server-side request forgery in OpenStack Glance through 32.0.0 allows remote authenticated users with admin rights to fetch internal URLs via import tasks. The deprecated /v2/tasks legacy import path accepts type=import requests and applies only a permissive http:// or https:// prefix check instead of the host and port restrictions enforced by import_filtering_opts for modern web-download imports. Reachability is limited to deployments that still expose the Tasks API; since Xena it is admin-only, and the published impact is confined to Glance-originated requests into the service network.
