## Affected

- TeamViewer Remote Management - Monitoring: fixed in 26.10.1

## Description

Improper authentication in the inter-process communication (IPC) mechanism of TeamViewer Remote Management Monitoring for Windows prior to version 26.10.1 allows a local authenticated attacker with low privileges to impersonate the IPC broker and cause the Monitoring service to execute arbitrary code with NT AUTHORITY\SYSTEM privileges, resulting in local privilege escalation.
