Description
OpenAM before 16.1.3 contains an authorization bypass vulnerability in the sessions REST endpoint query operation that allows realm administrators to list sessions of every realm. Attackers holding delegated RealmAdmin privileges can supply a _queryFilter naming another realm to disclose usernames, universal IDs, and session handles across tenant boundaries.
