Bad master cylinder

I notice the pedal is a little mushy at idle and especially when starting the pedal feels like it is fighting me and drops/rises from the floor when starting. I took a look underneath the dash and can see some wetness at the master cylinder inside at the firewall. The ABS light came on once too until I reset it with Forscan.

Should I replace the master by itself or does this mean the booster is bad too?

Thanks.
