CVE-2026-86689: CWE-319 Cleartext transmission of sensitive information in Bransys ELD
Bransys ELD is shipped with hardcoded MQTT credentials, which will grant read access to real-time data for every active device across a subset of carriers that were connected to the affected MQTT broker.
AI Analysis
Technical Summary
Bransys ELD contains hardcoded MQTT credentials that enable unauthorized read access to real-time data across multiple active devices connected to certain carriers' MQTT brokers. The vulnerability is due to cleartext transmission of sensitive information (CWE-319), which can be intercepted by attackers with network access. The affected versions include all releases prior to 11.00.00 and 1.1.54. There is no indication of known exploits in the wild or available patches at this time.
Potential Impact
An attacker who obtains the hardcoded MQTT credentials can read real-time data from all active devices connected to the affected MQTT broker for certain carriers. This compromises confidentiality of sensitive information but does not affect integrity or availability. The vulnerability is rated medium severity with a CVSS score of 5.9.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict network access to the MQTT broker and monitor for unauthorized access attempts. Avoid using hardcoded credentials and consider implementing encrypted communication channels to protect sensitive data.
