CVE-2026-86689Network attack vector

Remote telemetry disclosure via hardcoded MQTT credentials

Published Sep 18, 2026 · Updated Sep 18, 2026

Cleartext transmission in Bransys ELD Android before 11.00.00 and iOS before 1.1.54 allows remote attackers to read live device data. The affected mobile clients send embedded shared MQTT credentials without transport encryption, enabling broker access to data from every active device. Network reachability to the affected broker and access to an affected client build are required; exposure is limited to real-time data for connected carriers.
