• CVE-2023-50715: 0.91% estimated exploitation activity in the next 30 days; percentile 59.98 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

Summary The login page discloses all active user accounts to any unauthenticated browsing request originating on the Local Area Network. Details 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 (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, fd00::/8, ::ffff:10.0.0.0/104, ::ffff:172.16.0.0/108, ::ffff:192.168.0.0/112) The rationale behind this is to make the login more user-friendly (see release blog post) 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…

# Patch Next advisory brief: CVE-2023-50715

Advisory: User accounts disclosed to unauthenticated actors on the LAN
IDs: CVE-2023-50715, GHSA-jqpc-rc7g-vf83
Record: https://patchnext.com/advisories/cve-2023-50715 (revision 2, source checked 26 Oct 2026, 13:12 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: homeassistant 2023.12.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI homeassistant: affected < 2023.12.3; fixed in 2023.12.3

## Suggested inspection (read-only)
- `python -m pip show homeassistant`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on homeassistant.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
