There seems to be a leak in the ContactShadow determination in DeferredLightingCommon.ush ShadowRayCast(), but I could not determine if this is the specification.
This problem always occurs from 4.27 to now.
Apply a spotlight with cast shadow disabled to the hair material.
Light leakage occurs around the mesh with default material.
You can see it by opening NewMap.umap of the attached project.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-178541 in the post.
