Upgrade Debian:unstable nextcloud-desktop to version 3.6.1-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream nextcloud-desktop package and not the nextcloud-desktop package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
Nextcloud also ships a CLI utility called nextcloudcmd which is sometimes used for automated scripting and headless servers. Versions of nextcloudcmd prior to 3.6.1 would incorrectly trust invalid TLS certificates, which may enable a Man-in-the-middle attack that exposes sensitive data or credentials to a network attacker. This affects the CLI only. It does not affect the standard GUI desktop Nextcloud clients, and it does not affect the Nextcloud server.
