Wallet files in the "~/.config/Nano Desktop Wallet/backup" directory are stored with insecure permissions. Most systems have a default umask of 022 which results in 0644 as the default permissions of files. As a consequence, other users on the same system can read the contents of these files. Instead, it should only be readable by the owner of the file.
This is also an issue in the legacy desktop wallet. I reported it months ago in private. It was acknowledged, but never fixed.
