Summary
tangro Business Workflow before 1.18.1 requests a list of allowed filetypes from the server and restricts uploads to the filetypes contained in this list.

Summary
An issue was discovered in tangro Business Workflow before 1.18.1. No (or broken) access control checks exist on the /api/document/<DocumentID>/attachments API endpoint. Knowing a document ID, an attacker can list all the attachments of a workitem, including their respective IDs. This allows the attacker to gather valid attachment IDs for workitems that do not belong to them.
