I am able to reproduce it. For now Medium priority, but might become High depends on the cause.
Please find attach the simple blend file that demonstrates this. (not using HDRI, but a Point light.)

@Fortis-4, can you confirm that when you load factory setting the issue is gone? Seems like there was a change in the defaults.
After I reset the factory settings and create the scene from scratch I am not able to reproduce it.

I see you are using a blender build that is one week old. Can you retest this with the latest version. Issue could be in your version, but have already been fixed.

  1. download and install latest version from builder.blender.org
  2. start blender and reset factory settings
  3. create a scene from scratch (earlier created files could have this issue stored inside the files)
  4. check if problem still exist.

Thanks!

Isn't that the same old problem of low poly self-shadowing in Cycles? #37814

Indeed, you need to use more subdivisions, this is not considered a bug for now.

It is very sad, it is not always possible to use high-poly geometry.
