CyberVault Technical Summary

Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2026-26367 impacting jung-group enet_smart_home. Evaluated with CVSS Base Score of 8.1 (HIGH).

Original NVD Description

Source: NIST NVD
eNet SMART HOME server 2.2.1 and 2.3.1 contains a missing authorization vulnerability in the deleteUserAccount JSON-RPC method that permits any authenticated low-privileged user (UG_USER) to delete arbitrary user accounts, except for the built-in admin account. The application does not enforce role-based access control on this function, allowing a standard user to submit a crafted POST request to /jsonrpc/management specifying another username to have that account removed without elevated permissions or additional confirmation.
