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.
ApostropheCMS is an open-source Node.js content management system, and uploadfs is its file storage library. Prior to uploadfs 1.28.0, attacker-controlled paths that reach the local backend can contain parent-directory segments that escape the configured upload directory and affect file reads, writes, and deletion on the host filesystem. Exploitability depends on an application exposing the relevant uploadfs operations to untrusted path. This issue is fixed in uploadfs 1.28.0.
