CVE-2026-83597

Netdata: Local Privilege Escalation in Netdata Windows Agent installer via MSI Repair Execution

7.0 High

Netdata is an open source observability tool. From version 2.0.0 until 2.10.4, Netdata Windows Agent MSI repair launches powershell.exe and wevtutil.exe as elevated interactive processes in the initiating user's desktop session. A low-privileged local user who triggers repair can interact with or hijack those visible process windows to execute arbitrary commands with SYSTEM privileges. This issue is fixed in stable version 2.10.4.
