CVE-2026-113652 Details
Description
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.
A vulnerability in ApostropheCMS's Uploadfs Azure backend, present in versions 1.25.0 prior to 1.28.0, allows account-level SAS tokens to be leaked through public attachment URLs. When Uploadfs is configured with the Azure backend and SAS tokens are enabled, the BlobServiceClient is created from a URL that includes the full SAS query string. This string is then inherited by Azure SDK v12 clients, which exposes the SAS token in every public attachment link. As a result, anyone with access to the URL can read, overwrite, delete, and list all blobs in the container for the duration of the SAS token's validity.
Users can update to ApostropheCMS version 1.28.0 or later, where this vulnerability has been fixed.
