  "title": "Cross-project authorization flaw in OpenStack Mistral",
  "summary": "OpenStack Mistral v2 write operations can act on resources owned by a different project. An authenticated project member may alter or remove the public availability of another project's action definitions or environments; a project administrator may also trigger cross-project resource reassignment through a name collision. Only deployments that expose the Mistral API are affected.",
  "mitigation": "Upgrade Mistral to 20.1.1, 21.0.1, or 22.0.1, as appropriate for the deployed release line. Until upgraded, restrict Mistral API access to trusted networks and users.",
