- No exploitation in the wild and no public exploit is recorded for the CVEs named.
CISA published an ICS advisory for Bransys Electronic Logging Device (ELD) mobile applications used in the U.S. transportation sector. Three vulnerabilities affect Android versions before 11.00.00 and iOS versions before 1.1.54: hardcoded MQTT broker credentials (CVE-2026-86520) granting read access to real-time telemetry across a subset of connected carriers, cleartext transmission of sensitive data (CVE-2026-86689) allowing interception of broker traffic, and hardcoded FTP credentials (CVE-2026-77960) allowing unauthorized read access to stored data on the FTP server.
Successful exploitation would let an attacker without prior authentication read live telemetry and firmware-related data from affected devices, potentially exposing vehicle location, driver logs, and other ELD data across multiple carriers sharing the same broker infrastructure. CISA states no public exploitation of these specific vulnerabilities has been reported at this time. The vendor has released fixed versions (Android ≥11.00.00, iOS ≥1.1.54) available via the respective app stores, and CISA recommends standard network isolation practices (segmenting control system networks, avoiding direct internet exposure, and using VPNs for remote access) as compensating controls.
This is a vendor-disclosed vulnerability set affecting a niche but critical-infrastructure-adjacent product category (ELDs used for regulatory compliance in commercial trucking/transportation). Defenders in transportation/logistics should prioritize confirming app versions are updated and audit any exposure of MQTT/FTP services to unauthenticated networks.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
