{"cve":"CVE-2026-54317","nvd":{"published":"2026-06-23T18:18:08.767","modified":"2026-10-25T23:10:00.167","status":"Modified","description":"Home Assistant is open source home automation software that puts local control and privacy first. Prior to 2026.6.0, the Konnected integration registers an HTTP endpoint, KonnectedView (homeassistant/components/konnected/__init__.py), that is marked as not requiring authentication (requires_auth = False). A comment next to that line says auth is instead handled \"via the access token from configuration.\" That promise is only half true. Write requests (POST and PUT) are handled by update_sensor(), which does check the request's Authorization: Bearer <token> header against the integration's stored access tokens (using hmac.compare_digest). Read requests (GET) are handled by a separate get() method that has no authentication check at all. This vulnerability is fixed in 2026.6.0.","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:L/A:L","score":7.6},"cwes":["CWE-200","CWE-306"],"references":["https://github.com/home-assistant/core/security/advisories/GHSA-x84v-g949-293w","https://github.com/home-assistant/core/security/advisories/GHSA-x84v-g949-293w"],"products":["home-assistant:home-assistant"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-54317","score":0.00308,"percentile":0.23397,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-x84v-g949-293w","url":"https://osv.dev/vulnerability/GHSA-x84v-g949-293w","summary":"Home Assistant: Konnected alarm-panel switch state and zone topology disclosed to unauthenticated actors on the LAN","modified":"2026-07-20T21:30:45.011542887Z","packages":[{"ecosystem":"PyPI","name":"homeassistant","purl":"pkg:pypi/homeassistant","ranges":["<2026.6.0"],"fixed":["2026.6.0"]}]},{"id":"PYSEC-2026-241","url":"https://osv.dev/vulnerability/PYSEC-2026-241","summary":"","modified":"2026-06-27T11:15:05.236546757Z","packages":[{"ecosystem":"PyPI","name":"homeassistant","purl":"pkg:pypi/homeassistant","ranges":["<2026.6.0"],"fixed":["2026.6.0"]}]}],"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).
