# Patch Next advisory brief: CVE-2017-2673

Advisory: OpenStack Identity service (keystone) Incorrect Authorization
IDs: CVE-2017-2673, GHSA-j36m-hv43-7w7m
Record: https://patchnext.com/advisories/cve-2017-2673 (revision 3, source checked 26 Oct 2026, 13:30 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: keystone 11.0.1, 10.0.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI keystone: affected >= 9.0.0, <= 9.3.0; >= 10.0.0, <= 10.0.1; >= 11.0.0, <= 11.0.0; fixed in 11.0.1, 10.0.2

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

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on keystone.
- 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.
