Is this vulnerability remotely exploitable over the network?

Yes, if Focalboard is exposed over the network and an attacker can authenticate, they can exploit the affected API endpoints remotely, provided they have the necessary permissions to manipulate categories.

Does exploitation require authentication or special privileges?

Exploitation requires an authenticated user account with the ability to influence or create categories such that the category ID field can be controlled. Elevated privileges are not strictly required if standard users can trigger the affected operations.

What is the safest general fix pattern for this issue?

The most reliable fix pattern is to eliminate dynamic SQL string concatenation and use parameterized queries or prepared statements throughout, while enforcing strict typing and validation for category IDs and related fields, even when values are read back from the database.
