Is this vulnerability remotely exploitable?

It is primarily a local vulnerability. An attacker must be able to interact with the affected system and supply a crafted password to the Orbit GUI dialog that triggers the FileVault key rotation flow. There is no direct remote network vector described.

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

The attacker needs local, unprivileged user access on a system where Orbit is installed and the FileVault key rotation feature is available. They must be able to initiate the rotation flow and enter a password in the dialog.

What is the safest general fix pattern for this class of bug?

The safest approach is to eliminate dynamic script construction with embedded user input. Instead, pass user-derived data to interpreters or system utilities through parameterized interfaces (arguments, stdin, environment variables) that treat it strictly as data, or replace the interpreter usage with direct API calls that do not require quoting or escaping.
