## Overview

Therefore Corporation GmbH has recently become aware that Therefore™ Online and Therefore™ On-Premises contain an account impersonation vulnerability. A malicious user may potentially be able to impersonate the web service account or the account of a service using the API when connecting to the Therefore™ Server. If the malicious user gains this impersonation user access, then it is possible for them to access the documents stored in Therefore™. This impersonation is at application level (Therefore access level), not the operating system level.
