This is becoming more common, it's not actually the struts that are leaking, but rather the lift system. Don't leave your car in lifted mode after you pull it into your garage, let it sit lowered. You can top off the power steering fluid (CHF-202 or CHF-11S) if it's starting to get low. It's not a safety issue because it only affects the lift system, the less time you spend lifted the less it will weep. Just make sure your power steering fluid is topped off and you'll be fine until the part comes in as long as the puddling stops when you keep it lowered.
