OpenStack Cinder Denial of Service using XML entities

CVE-2013-4202GHSA-mfg4-9xf4-f45q

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (cinder 7.0.0a0), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

The (1) backup (api/contrib/backups.py) and (2) volume transfer (contrib/volumetransfer.py) APIs in OpenStack Cinder Grizzly 2013.1.3 and earlier allows remote attackers to cause a denial of service (resource consumption and crash) via an XML Entity Expansion (XEE) attack. NOTE: this issue is due to an incomplete fix for CVE-2013-1664.

# Patch Next advisory brief: CVE-2013-4202

Advisory: OpenStack Cinder Denial of Service using XML entities
IDs: CVE-2013-4202, GHSA-mfg4-9xf4-f45q
Record: https://patchnext.com/advisories/cve-2013-4202 (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: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: cinder 7.0.0a0. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI cinder: affected < 7.0.0a0; fixed in 7.0.0a0

## Suggested inspection (read-only)
- `python -m pip show cinder`: 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 cinder.
- 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.
