I would be concerned because it will only get worse. I would try patching the wall from the inside with hydraulic cement. If that doesn't work, you'll have to dig down outside the house to fix the crack from the outside and apply waterproofing to the concrete block.

Before that, check to make sure you've got good gutters and slope dirt away from the house to encourage water to stay away.

The way to fix the crack itself is using a concrete injection kit from the inside. You will not have to fix this from the outside by digging down at all. Ensuring water isn't pooling by your foundation is also something to do. But this isn't a concerning crack at all.

This is what I used Super easy, you can watch the stuff expand out the top of the foundation wall on the outside as proof it makes it all the way through.

Fix your grading to prevent water flowing towards to the house.

I used hydraulic cement for this same issue in my house. I also dug a French drain outside for the downspout about 6 feet from the house. It's best to do this now before it gets worse. You don't want mold or mildew buildup starting either.
