Is this vulnerability remotely exploitable over the internet?

Yes, if WeKnora is exposed over the network and the vulnerable query endpoints are reachable, a remote attacker can exploit the flaw without needing local access to the database host.

Does an attacker need authentication or a valid account to exploit this?

Not necessarily. If the affected endpoints accept input from unauthenticated users, exploitation can be fully unauthenticated. In deployments where access is restricted, an attacker would first need credentials or access to a trusted integration point.

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

Replace dynamic SQL string assembly with parameterized queries or structured query builders that keep query structure fixed and treat all user-controlled input as data. Any validation logic should operate on a structured representation of the query and traverse it recursively, rather than relying on shallow pattern matching.
