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's TensorZero deployment has authentication enabled, only authenticated callers can exploit this vulnerability. If a developer's 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.","public_affected_ranges":["< 2026.6.0"]}],"null_published_at":"2026-11-04T10:04:27.868Z","source_updated_at":"2026-07-15T21:59:41.000Z","source_disclosed_at":"2026-07-15T21:59:40.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-04T09:59:43.724Z"}],"next_cursor":null,"snapshot_revision":"42594"}
