CVE-2026-92370Network attack vectorHinoki check available

Unauthorized remote actions via session permission bypass

Published Sep 29, 2026 · Updated Sep 29, 2026

Improper access control in TeamViewer Full Client and Host before 15.82 allows remote authenticated users to bypass session permissions. During session establishment, the clients accept attacker-modified access-control parameters for restricted features instead of enforcing the target's configured permissions. The bypass requires an authenticated remote session and user interaction; it permits denied actions and can lead to code execution on the target.
