ᐅ Mistakes Drilling into Sand-Lime Brick up to Exterior Insulation and Finish Systems (EIFS)

Hello,
first of all: I am a construction layman. Here is my situation:
- The picture shows the bathroom in the attic
- The wall is made of calcium silicate bricks
- In the center of the picture there is a mistaken drill hole that reaches all the way to the exterior-applied rigid foam insulation system (ETICS / external thermal insulation composite system), but does not damage it (visible through the hole)
- In front of this is the vanity stud wall made of drywall panels
- The drywall stud wall will be filled with insulation wool
Now the question:
Does this drill hole, if left unfilled, create a thermal bridge or is it unproblematic since the external insulation system is still intact?
- Would the airtightness then be compromised?
Thanks to everyone! 😉

I was at the house again. The scaffold anchors are not the issue; they are still in place and at a different height.
So, it’s still not a problem if one side is plastered and there’s external thermal insulation composite system (ETICS / EWI) on the outside?
Thanks and have a great rest of the weekend.

Not just the hole, but all other mortar joints as well.
