## Overview

In Progress® Telerik® Report Server prior to version 12.2.26.1007, incorrect privilege assignment in the service-agent SignalR hub allows an authenticated user, including a low-privilege or guest account with a valid bearer token, to register as a trusted service agent. On the next server settings-synchronization event, the rogue agent receives storage settings and encryption private keys. This privilege escalation enables disclosure of protected secrets, including stored data-source credentials and connection strings, and allows agent impersonation and interference with task dispatch.
