If an external user is given an owner role on any group, that external user may escalate their privileges on the instance by creating a service account in that group.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.68%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
