It seems early for a brake line rustout. Look for the wet spot under the safely jacked and supported vehicle.
This diagram is a parts drawing from moparpartsgiant.com. The leak may be in lines #2 or #3? It may be underneath the protective plastic line shields #11 and #12. Or perhaps ahead of that at lines #4 and #5? Note the FWD-pointing arrow in the image.
The upper image is the rear half of the brake lines. The lower image is for the front half of the brake lines.

Locally, we lose about 1 person each year to a vehicle slipping off a jack. This is an entirely preventable loss, full of 'if-onlys'.
The KIA/Hyundai and Subarus have had multiple recalls for rusted brake/fuel lines. They don't use road salt in these countries, so corrosion is rampant here.

Sometimes the plastic shielding meant to protect the lines can hold wet salty/sandy debris inside and rot the lines quicker.

KIA sells the brake/fuel lines as a pre-formed bundle. They individual lines aren't serviced separately. This makes sense as when one line lets go, the others usually aren't far behind.
