  "title": "Missing cluster authorization in GPUStack model-file creation",
  "summary": "GPUStack versions before 2.3.0 do not enforce cluster-management permission when creating model-file download jobs. An authenticated Organization Owner may cause a chosen worker outside their authorized management scope to download files to a selected writable location, provided they know the worker ID and the worker can access the selected source.",
  "mitigation": "Upgrade the gpustack package to version 2.3.0 or later. Until upgraded, restrict Organization Owner access and limit workers' writable filesystem locations and model-source access.",
