A user with write access to the releases of a repository, who knew the UUID of an attachment in that repository, could link it to a release. This exposed the file name, size and download count of the attachment through the release and allowed the user to rename or delete it.","summary":"Adding an attachment to a release did not check whether the attachment was already linked to an issue or comment.
