Does this matter?

Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.

Description

Attackers holding delegated RealmAdmin privileges can supply a _queryFilter naming another realm to disclose usernames, universal IDs, and session handles across tenant boundaries.
