DescriptionThe mechanism binding API-uploaded files to the uploader's authentication method is not working correctly and the same session token is used for all token-based API users. Since API-uploaded files are refered to by randomly generated UUIDs and only exist for a day, there is virtually no risk, but it renders the added protection mechanism useless.
