  "details": "### Impact\n\nThe `/internal/object_storage` endpoint accepts a caller-supplied JSON `storage_path` parameter that dynamically overrides the TensorZero `[object_storage]` configuration.\n\nBy abusing the `filesystem` storage type, a caller can read arbitrary files from the gateway filesystem, including files that may contain sensitive credentials. Similarly, by abusing the `s3_compatible` storage type, the caller can coerce the gateway into making outbound object storage requests to attacker-chosen internal/cloud-metadata endpoints.\n\nThis vulnerability only applies when the gateway can be accessed by untrusted callers. If a developer\u0027s TensorZero deployment has authentication enabled, only authenticated callers can exploit this vulnerability. If a developer\u0027s deployment has authentication disabled, any caller can exploit this vulnerability.\n\n### Remediation\n\nThe vulnerability has been patched in version `2026.6.0`. See PR #7527.\n\n### Workarounds\n\nIf developers are unable to upgrade a gateway that is exposed to untrusted callers, please block external access to the `/internal/object_storage` endpoint.",
