Well, we can't tell; I added the caveat first go that presuming OP did
indeed verify this is a continuous connection back to the neutral bus, not
the ground. If that really is the case, it isn't unsafe electrically,
just not Code-compliant on the colors.

It could quite easily be a two-wire circuit in the time frame which are
grandfathered.

It's not connected to the neutral buss. It's connected to the circuit
breaker. It's being used as a hot leg, not neutral.
