CVE-2026-83598: Netdata

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Netdata Netdata: from 2.0.0, before 2.10.4 (fixed in 2.10.4)
