Effected devices have been mitigated through an automatic update beyond the affected range.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-287"],"references":["https://support.google.com/product-documentation/answer/13588832?hl=en&ref_topic=12974021&sjid=7833436865896465963-NA#zippy=%2Cnest-wifi","https://support.google.com/product-documentation/answer/13588832?hl=en&ref_topic=12974021&sjid=7833436865896465963-NA#zippy=%2Cnest-wifi"],"products":["google:nest_hub_firmware","google:nest_hub_max_firmware","google:nest_wifi_6e_firmware","google:nest_wifi_point_firmware","google:wifi_firmware"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-2626","score":0.00115,"percentile":0.0154,"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).
