Description

An SSRF issue was discovered in OpenStack Glance before Newton. The 'copy_from' feature in the Image Service API v1 allowed an attacker to perform masked network port scans. With v1, it is possible to create images with a URL such as 'http://localhost:22'. This could then allow an attacker to enumerate internal network details while appearing masked, since the scan would appear to originate from the Glance Image service.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for glance, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update glance to 11.0.0a0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-j6mr-cm6x-h6jg is resolved across your whole dependency graph.

  3. Workarounds

    Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.
