CVE-2026-26366Public exploitNetwork attack vector

Administrative access via unchanged default credentials

Published Feb 15, 2026 · Updated Feb 15, 2026

Use of default credentials in JUNG eNet SMART HOME Server 2.2.1 and 2.3.1 allows remote attackers to gain administrative access. The server retains the shipped user:user and admin:admin credentials after installation and commissioning because it does not require a password change. Network access is sufficient to authenticate with a default account and control or alter sensitive smart-home configuration.
