Is this vulnerability remotely exploitable?

It is exploitable through the management interface or API that exposes the restore function, but only by users who already hold the NetworkManager (or similarly privileged) role. It is not a fully unauthenticated remote exploit; it requires legitimate access to that role.

What level of access does an attacker need to exploit this issue?

An attacker must be authenticated as a NetworkManager or any role configured with backup and restore permissions. From there, they can upload a crafted SQLite database that alters stored authorization data and elevates their privileges to Admin.

What is the safest general fix pattern?

The safest pattern is to remove restore permissions from non-administrative roles and treat restore as a highly privileged, tightly controlled operation. Supplement this by enforcing integrity checks on backups and validating that restored data does not violate core authorization rules.
