How to fix?

Upgrade Debian:10 fuse to version 2.8.5-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream fuse package and not the fuse package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

Certain legacy functionality in fusermount in fuse 2.8.5 and earlier, when util-linux does not support the --no-canonicalize option, allows local users to bypass intended access restrictions and unmount arbitrary directories via a symlink attack.
