CVE-2026-77960Network attack vector

Live telemetry disclosure via hardcoded MQTT credentials

Published Sep 18, 2026 · Updated Sep 18, 2026

Hard-coded credentials in Bransys ELD before 11.00.00 on Android and before 1.1.54 on iOS allow remote attackers to read live device data. The mobile clients embed shared MQTT credentials that authenticate to an affected broker and expose real-time data for every active device across connected carriers. No prior authentication or user interaction is required; access is limited to reading broker data, with no reported ability to alter it or interrupt service.
