{"id":"CVE-2026-83598","summary":"Netdata: Local Privilege Escalation in Netdata Agent Windows installer via PowerShell Profile Hijack in MSI Repair","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.","aliases":["GHSA-8hxv-2mg6-ggw5"],"modified":"2026-09-24T03:46:27.364667247Z","published":"2026-09-22T17:04:21.953Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-269","CWE-427"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/83xxx/CVE-2026-83598.json"},"references":[{"type":"WEB","url":"https://github.com/netdata/netdata/releases/tag/v2.10.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/83xxx/CVE-2026-83598.json"},{"type":"ADVISORY","url":"https://github.com/netdata/netdata/security/advisories/GHSA-8hxv-2mg6-ggw5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-83598"},{"type":"FIX","url":"https://github.com/netdata/netdata/commit/d762782697623a98b51b4e41f7fe2d12404f0662"},{"type":"FIX","url":"https://github.com/netdata/netdata/pull/22751"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/netdata/netdata","events":[{"introduced":"92b67c5bfd8ee40b4443ce3911608a2d91a50a24"},{"fixed":"d762782697623a98b51b4e41f7fe2d12404f0662"},{"fixed":"245283237171400672a9ad914f5785ba8bc0fa5c"}],"database_specific":{"extracted_events":[{"introduced":"2.0.0"},{"fixed":"2.10.4"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v2.10.3","v2.10.2","v2.10.1","v2.10.0","v2.9.0","v2.8.0","v2.7.0","v2.6.0","v2.5.0","v2.4.0","v2.3.0","v2.2.0","v2.1.0","v2.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/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"}]}
