In contact is much different than submerged or something. The inner wires are all coated in plastic so water will have no impact on them. The only worry is over a long period of time something in the water may damage the plastic. I would cut a few inches off the end and you are likely good since it is unlikely water managed to fill the cable for some long distance. I have run indoor cable outdoors for many years and so far have had no issues. Likely at some point I will get a failure but it is getting on 5 yrs for one of them and that one runs up a 30ft tower in both the sun and the rain.
