Nextcloud Mail is the mail app for Nextcloud, a self-hosted productivity platform. The Nextcloud mail app incorrectly allowed attaching shared files without download permissions as attachments. This allowed users to send them the files to themselves and then downloading it from their mail clients. It is recommended that the Nextcloud Mail is upgraded to 2.2.10, 3.6.2 or 3.7.2.
