FKIE_CVE-2026-47721

Vulnerability from fkie_nvd - Published: 2026-08-18 20:17 - Updated: 2026-08-19 16:17
Severity
6.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
Summary
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.2, POST /api/scheduler and DELETE /api/scheduler in server/api/scheduler/index.js do not consistently enforce authJwt.haveAdminPermission for scheduler settings. An authenticated non-admin operator can create or alter deviceActions that invoke onSetValue or onRunScript, or delete schedules, gaining access to device-value changes and server-side project script execution normally reserved for administrators. Scheduled and repeating actions can continue changing PLC setpoints, safety interlocks, device state, or project data after the operator's session ends. This issue is fixed in version 1.3.2.
