2011 CTS-V rear shock leaking oil

I have a 2011 CTS-V Wagon with only 31 K miles on it (obviously not my daily driver) and the left rear shock started dripping/leaking a clear lightweight oil which is probably the hydraulic oil used within the gas-charged shocks on this vehicle. My question is whether or not I need to replace both rear shocks since the right one seems perfectly OK and this is a fairly low-mileage vehicle. Any sage advice or comments on this situation…?
