CVE-2026-26369Public exploitNetwork attack vector

Authenticated administrator escalation via unchecked group assignment

Published Feb 15, 2026 · Updated Feb 15, 2026

Improper privilege management in JUNG eNet SMART HOME Server 2.2.1 and 2.3.1 allows remote authenticated users to gain administrator access. The setUserGroup method at /jsonrpc/management accepts a caller-controlled userName and UG_ADMIN group without enforcing the caller's UG_USER authorization. Any low-privileged account can promote itself and then modify device configurations, network settings, and other server-managed smart-home functions.
