CVE-2026-83598: Improper privilege management vulnerability

Netdata is an open source observability tool. From rom 2.0.0 until 2.10.4, during Netdata Windows Agent MSI repair, powershell.exe runs as SYSTEM without -NoProfile and loads %USERPROFILE%\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1 from the low-privileged user who initiated repair. Commands placed in that profile before repair therefore execute with SYSTEM privileges. This vulnerability is fixed in 2.10.4.
