CVE-2026-86520: CWE-798 Use of Hard-coded Credentials 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
CVE-2026-86520 is a vulnerability in Bransys ELD caused by the use of hardcoded MQTT credentials (CWE-798). These credentials provide read access to real-time data for every active device connected to the affected MQTT broker across a subset of carriers. The vulnerability affects Bransys ELD versions prior to 11.00.00 and prior to 1.1.54. The CVSS v3.1 score is 7.5, reflecting high severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed. This vulnerability does not impact integrity or availability, only confidentiality.
Potential Impact
An attacker can use the hardcoded MQTT credentials to gain unauthorized read access to real-time data from all active devices connected to the affected MQTT broker. This compromises the confidentiality of the data but does not affect integrity or availability. The exposure is limited to a subset of carriers connected to the broker.
Mitigation Recommendations
No official patch or remediation details are provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restricting network access to the MQTT broker and monitoring for unauthorized access may help reduce risk.
