Name of the Vulnerable Software and Affected Versions Home Assistant versions prior to 2023.12.3

Description The login page of Home Assistant discloses all active user accounts to any unauthenticated browsing request originating on the Local Area Network. 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. However, 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.

Recommendations Update to version 2023.12.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the login page to minimize the risk of exploitation.
