CVE-2026-106145
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk3th percentile - higher than 3% of all known CVEs
Summary
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.
Risk Assessment
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. This may lead to data compromise and service disruption.
Recommendation
Update Telerik Report Server to version 12.2.26.1007 or later. If possible, disable or restrict access to the service-agent SignalR hub and rotate any exposed keys and credentials.
