What is CVE-2026-27843?

CVE-2026-27843 is a critical missing authorization vulnerability in SenseLive X3050, published on 23 Apr 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official 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.
