EPSS

• CVE-2017-7200: 2.06% estimated exploitation activity in the next 30 days; percentile 81.32 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

An SSRF issue was discovered in OpenStack Glance before Newton. The 'copyfrom' 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.

# Patch Next advisory brief: CVE-2017-7200

Advisory: OpenStack Glance Server-Side Request Forgery (SSRF)
IDs: CVE-2017-7200, GHSA-j6mr-cm6x-h6jg
Record: https://patchnext.com/advisories/cve-2017-7200 (revision 2, source checked 26 Oct 2026, 13:13 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: glance 11.0.0a0. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI glance: affected < 11.0.0a0; fixed in 11.0.0a0

## Suggested inspection (read-only)
- `python -m pip show glance`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on glance.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
