TL;DR

Affected versions of Spring gRPC are vulnerable to Improper Isolation or Compartmentalization. When an authenticated user is denied access to a gRPC method, their authenticated identity remains bound to the gRPC worker thread and can be inherited by a subsequent unauthenticated request on the same thread. This may allow the subsequent user to gain escalated permissions.

Who does this affect?

You are affected if using a vulnerable version.
