CVE-2026-61892 · Severity: high · CVSS 8.8 · Published 2026-07-24

Weintek cMT3092X Human-Machine Interface (HMI) devices, which are used to control industrial machinery, contain a security flaw that allows a user with low-level access to escalate their privileges. By modifying security tokens, an attacker could gain full control over the device's settings and operations. This could lead to unauthorized changes in industrial processes, data theft, or service disruptions in critical manufacturing environments.
