This may allow attackers to interfere with firmware updates, access device functionality exposed by the platform, or disrupt device connectivity.\n\nIn environments where additional features such as remote console access are enabled, this could lead to full compromise of affected devices.\n\nThis issue affects nerves_hub_web: from 1.0.0 before 2.4.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":9.4},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-285","CWE-668"],"references":["https://cna.erlef.org/cves/CVE-2026-28806.html","https://github.com/nerves-hub/nerves_hub_web/commit/1f69c9d595684a4650c3ac702f3dc7c5bcd7526c","https://github.com/nerves-hub/nerves_hub_web/security/advisories/GHSA-f8fr-mccc-xvcx","https://osv.dev/vulnerability/EEF-CVE-2026-28806"],"products":["nerves-hub:nerveshub"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-28806","score":0.00426,"percentile":0.36926,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
