## Description

An improper access control vulnerability in the IPC communication between TeamViewer Full Client or Host prior to version 15.83 and the Remote Management Monitoring component prior to version 26.10.1 allows a local authenticated attacker with low privileges to execute scripts as SYSTEM/root.

## What to do

- Check your stack: if you ship or depend on TeamViewer Full Client, TeamViewer Host, TeamViewer Remote Management - Monitoring, upgrade to a fixed version (15.83, 15.64.10 (Legacy Windows 7 & 8), 14.7.48868 (Windows), 14.7.48868 (Linux), 14.7.48868 (macOS)) per the references below.
