CVE-2026-26367 — Jung-Group Enet Smart Home security vulnerability

High CVSS 8.1

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.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
