{"cve":"CVE-2023-50715","nvd":{"published":"2023-12-15T03:15:45.127","modified":"2026-06-17T06:39:50.470","status":"Modified","description":"Home Assistant is open source home automation software. Prior to version 2023.12.3, the login page discloses all active user accounts to any unauthenticated browsing request originating on the Local Area Network. Version 2023.12.3 contains a patch for this issue.\n\nWhen starting the Home Assistant 2023.12 release, the login page returns all currently active user accounts to browsing requests from the Local Area Network. Tests showed that this occurs when the request is not authenticated and the request originated locally, meaning on the Home Assistant host local subnet or any other private subnet. The rationale behind this is to make the login more user-friendly and an experience better aligned with other applications that have multiple user-profiles.\n\nHowever, as a result, all accounts are displayed regardless of them having logged in or not and for any device that navigates to the server. This disclosure is mitigated by the fact that it only occurs for requests originating from a LAN address. But note that this applies to the local subnet where Home Assistant resides and to any private subnet that can reach it.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-200"],"references":["https://github.com/home-assistant/core/commit/dbfc5ea8f96bde6cd165892f5a6a6f9a65731c76","https://github.com/home-assistant/core/security/advisories/GHSA-jqpc-rc7g-vf83","https://github.com/home-assistant/core/commit/dbfc5ea8f96bde6cd165892f5a6a6f9a65731c76","https://github.com/home-assistant/core/security/advisories/GHSA-jqpc-rc7g-vf83"],"products":["home-assistant:home-assistant"],"source":"nvd","synced_at":"2026-10-19T21:42:34.585441961+00:00"},"epss":{"cve":"CVE-2023-50715","score":0.00908,"percentile":0.59939,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-jqpc-rc7g-vf83","url":"https://osv.dev/vulnerability/GHSA-jqpc-rc7g-vf83","summary":"User accounts disclosed to unauthenticated actors on the LAN","modified":"2026-07-07T17:57:34.425182124Z","packages":[{"ecosystem":"PyPI","name":"homeassistant","purl":"pkg:pypi/homeassistant","ranges":["<2023.12.3"],"fixed":["2023.12.3"]}]},{"id":"PYSEC-2026-1451","url":"https://osv.dev/vulnerability/PYSEC-2026-1451","summary":"User accounts disclosed to unauthenticated actors on the LAN","modified":"2026-07-07T17:47:43.476836146Z","packages":[{"ecosystem":"PyPI","name":"homeassistant","purl":"pkg:pypi/homeassistant","ranges":["<2023.12.3"],"fixed":["2023.12.3"]}]}],"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).
