CVE-2026-106145

Privilege Escalation in Telerik Report Server Service-Agent Hub

Published Oct 9, 2026 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed
Description
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.
