# CVE-2026-27843

> Vulnerability · severity: **CRITICAL** (CVSS 9.1).

## Description

A vulnerability exists in SenseLive X3050's web management interface that allows critical configuration parameters to be modified without sufficient authentication or server-side validation. By applying unsupported or disruptive values to recovery mechanisms and network settings, an attacker can induce a persistent lockout state. Because the device lacks a physical reset button, recovery requires specialized technical access via the console to perform a factory reset, resulting in a total denial-of-service for the gateway and its connected RS-485 downstream systems.
