GoKawiilTeamViewer patches five high-severity flaws in client and host software
TeamViewer issued an advisory urging all users to update to version 15.82 after fixing five high-severity vulnerabilities, including an access control bypass that could enable remote code execution and other flaws allowing privilege escalation to SYSTEM or root. The company says it has no evidence of public exploit code or active exploitation of the issues.
GoKawiil's interpretation of the reporting above, not reported fact.
TeamViewer's remote access tools are widely used by IT support staff but are also a known target for ransomware gangs seeking easy remote entry into corporate networks, so unpatched systems could become an attractive attack vector. The urgency of the advisory suggests the company views the access control bypass as particularly risky if weaponized before organizations apply the update.
- Five high-severity vulnerabilities were patched in TeamViewer Full Client and Host software.
- The most severe flaw, CVE-2026-92370, could allow remote code execution via an access control bypass.
- TeamViewer says there's no known public exploit or active exploitation yet, but urges immediate updating to version 15.82.
