CVE-2026-92375: TeamViewer improper IPC access control in Remote Management Monitoring

CVE-2026-92375 · Severity: high · CVSS 7.8 · Published 2026-10-27

TeamViewer's Remote Management components, which monitor and manage corporate IT infrastructure, contain local privilege escalation flaws that allow low-privilege authenticated users to execute commands with system-level permissions. An attacker with basic local access could gain complete system control, enabling them to compromise endpoint security, install malware, or move laterally within a network.

Technologies: Teamviewer Full Client, Teamviewer Host, Teamviewer Remote Management Monitoring. Vendors: Teamviewer.

Technical details

The vulnerability stems from improper access control in inter-process communication (IPC) between TeamViewer Full Client/Host and the Remote Management Monitoring component, allowing an authenticated local attacker to escalate privileges. The IPC mechanism fails to properly validate client identity or enforce access restrictions, enabling script execution as SYSTEM/root without user interaction. A fix is available in TeamViewer 15.83 and Remote Management Monitoring 26.10.1.
