{"id":"UBUNTU-CVE-2026-83598","details":"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.","modified":"2026-09-24T02:01:05.158822302Z","published":"2026-09-22T17:17:00Z","upstream":["CVE-2026-83598"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-83598"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-83598"},{"type":"REPORT","url":"https://github.com/netdata/netdata/commit/d762782697623a98b51b4e41f7fe2d12404f0662"},{"type":"REPORT","url":"https://github.com/netdata/netdata/pull/22751"},{"type":"REPORT","url":"https://github.com/netdata/netdata/releases/tag/v2.10.4"},{"type":"REPORT","url":"https://github.com/netdata/netdata/security/advisories/GHSA-8hxv-2mg6-ggw5"}],"affected":[{"package":{"name":"netdata","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/netdata?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.0+dfsg-1","1.8.0+dfsg-1","1.9.0+dfsg-1","1.9.0+dfsg-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"netdata","binary_version":"1.9.0+dfsg-1ubuntu0.1~esm1"},{"binary_name":"netdata-data","binary_version":"1.9.0+dfsg-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-83598.json"}},{"package":{"name":"netdata","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/netdata?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.16.1-2","1.19.0-3ubuntu1","1.19.0-3ubuntu1+esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.19.0-3ubuntu1+esm1","binary_name":"netdata"},{"binary_name":"netdata-apache2","binary_version":"1.19.0-3ubuntu1+esm1"},{"binary_name":"netdata-core","binary_version":"1.19.0-3ubuntu1+esm1"},{"binary_version":"1.19.0-3ubuntu1+esm1","binary_name":"netdata-plugins-bash"},{"binary_version":"1.19.0-3ubuntu1+esm1","binary_name":"netdata-plugins-nodejs"},{"binary_name":"netdata-plugins-python","binary_version":"1.19.0-3ubuntu1+esm1"},{"binary_version":"1.19.0-3ubuntu1+esm1","binary_name":"netdata-web"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-83598.json"}},{"package":{"name":"netdata","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/netdata?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.29.3-4","1.31.0-4","1.33.1-1ubuntu1","1.33.1-1ubuntu1+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"netdata","binary_version":"1.33.1-1ubuntu1+esm1"},{"binary_name":"netdata-apache2","binary_version":"1.33.1-1ubuntu1+esm1"},{"binary_name":"netdata-core","binary_version":"1.33.1-1ubuntu1+esm1"},{"binary_name":"netdata-plugins-bash","binary_version":"1.33.1-1ubuntu1+esm1"},{"binary_version":"1.33.1-1ubuntu1+esm1","binary_name":"netdata-plugins-nodejs"},{"binary_name":"netdata-plugins-python","binary_version":"1.33.1-1ubuntu1+esm1"},{"binary_version":"1.33.1-1ubuntu1+esm1","binary_name":"netdata-web"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-83598.json"}},{"package":{"name":"netdata","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/netdata?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.42.1-1","1.43.1-1","1.43.2-1","1.43.2-1build1","1.43.2-1build2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.43.2-1build2","binary_name":"netdata"},{"binary_version":"1.43.2-1build2","binary_name":"netdata-apache2"},{"binary_name":"netdata-core","binary_version":"1.43.2-1build2"},{"binary_name":"netdata-plugins-bash","binary_version":"1.43.2-1build2"},{"binary_version":"1.43.2-1build2","binary_name":"netdata-plugins-python"},{"binary_name":"netdata-web","binary_version":"1.43.2-1build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-83598.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
