TeamViewer urges users to patch five severe flaws now
TeamViewer is asking customers to update their remote access software "as soon as possible" after fixing five high-severity vulnerabilities in its client and host products. The company published the advisory on Tuesday. It is unusual for TeamViewer to push users this directly to secure their systems.
The flaws affect TeamViewer Full Client and Host, along with related services. The fixes ship in TeamViewer version 15.82 and in supported maintenance and legacy releases.
Access control bypass tops the list
The most serious issue is CVE-2026-92370, a remote session access control bypass. It comes from an improper access control weakness in TeamViewer Full Client and Host on Windows, Linux and macOS.
