From 1.25.0 until 1.28.0, uploadfs Azure backend leaks account-level SAS token into every public attachment URL. When uploadfs is configured with the Azure backend and sas: true, createContainer() builds the BlobServiceClient from a URL that embeds the full SAS query string, and Azure SDK v12 derived clients inherit that query string.
