CVE-2026-19743

Improper Limitation of a Pathname to a Restricted Directory (Path Traversal) in TeamViewer Desktop Clients PUBLISHED

Description (CNA)

Improper path validation in the local IPC service of TeamViewer Full Client and Host on Windows, Linux, and macOS prior to version 15.82 allows a local authenticated user with low privileges to perform arbitrary file writes with elevated privileges (NT AUTHORITY/SYSTEM \ root). By sending crafted IPC commands to the local service daemon, an attacker could manipulate file paths, leading to local privilege escalation.
