This sometimes happens when a bike is trailered and the forks stay compressed for a long time. The seal hasn't necessarily blown out, but because it stayed pressurized for so long, fork oil seeped out over the long trip.
I'd just check your fork oil level and as long as the seals haven't actually blown out, you may be OK.
Remember, you've no idea exactly how much oil you've lost and even small changes in fork oil levels can make for big changes in how the bike handles. I would not ride it in any brisk manner until you get the forks checked out. And remember also that the only way to accurately fill the forks is by opening them up, following procedure, and actually measuring the level. For instance, simply draining and putting in what came out is no good as is draining and putting in what the manual says they hold. Neither way is accurate. ALWAYS measure. And use good quality, full synthetic, racing grade fork oil. It's not that expensive and you don't need that much. It'll perform better and last longer.
And should you actually need new fork seals, make sure you use original factory seals. Aftermarket seals almost always suck and end up leaking. Spend a few more bucks and know that they're going to work and last.
