Show the technical text from the sources

Adding attachments to a release checked the repository and release of an attachment but not whether it was already linked to an issue or comment. 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.
