My cabinets are less than three years old and I noticed all of these blue circles this morning. The cabinets are white so these are pretty noticeable. Is this showing through the finish somehow? Is there any way to fix this?
This pattern looks like bubble wrap.
As such, it has probably been present since the cabinets were installed and the spot you're seeing may have been a pressure point where the wrap was strapped or secured to hold the cabinet in place for transport. It's hard to tell whether the white surface of the cabinets has another color bleeding through from behind, the white finish is damaged/thinned by contact with the bubble wrap, or some color from a non-transparent bubble wrap has leeched into the white finish.
Anyway, try wiping with cloth with a gentle soap solution and see if it comes off easily. If it does not, you could try an abrasive sponge (Magic Eraser) or harsher soaps and chemicals. Try these on a hidden or not noticeable section first. If the problem gets worse instead of better, it may be a finish below the white that's bleeding through a thin white layer (that's getting thinner as you scrub), and you'll probably need to refinish the cabinets. Hopefully it's just on the surface and you can scrub it away and be done.
