Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.

Description

A low-privileged authenticated user with read-only Security Solution access could perform write operations on watchlist data that should require elevated privileges. Under specific deployment conditions, this could also allow such a user to access data beyond their authorized scope.
