ApostropheCMS uploadfs Azure backend leaks account-level SAS token into every public attachment URL (sas: true)
ApostropheCMS is an open-source Node.js content management system. 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. This issue is fixed in version 1.28.0.
