CVE-2026-83598: Netdata Windows Agent MSI privilege escalation during repair

Technical details

During MSI repair, powershell.exe is launched as SYSTEM without the -NoProfile flag, causing it to load the user's PowerShell profile from %USERPROFILE%\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1. A low-privileged attacker can pre-populate this profile with arbitrary commands that execute with SYSTEM privileges when a repair is triggered. This is a local privilege escalation requiring user interaction (repair initiation) by an administrator.
