  "title": "Missing authentication in AIStore token revocation",
  "summary": "NVIDIA AIStore deployments expose a token-revocation endpoint without required authentication. A remote unauthenticated party can submit revocation-list data, potentially altering data and disrupting service; exposure requires the endpoint to be reachable by the attacker.",
  "mitigation": "Restrict network access to the token-revocation endpoint to trusted administrative systems using firewall or proxy controls. Obtain and deploy NVIDIA's corrective update when available; the supplied evidence does not name a fixed release.",
