Technical Analysis
CVE-2026-69658 affects Ebyte NA111-M firmware version 9013-2-17. The firmware transmits MQTT credentials and control traffic without encryption, leading to exposure of sensitive information on the network. This cleartext transmission (CWE-319) enables attackers to intercept credentials and potentially impersonate devices or disrupt messaging. The vulnerability has a CVSS 3.1 base score of 9.8, indicating critical severity with network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability.
Potential Impact
Attackers on the same network can intercept MQTT credentials and control messages, enabling unauthorized device impersonation and disruption of messaging functions. This compromises device authentication and message integrity, potentially leading to denial of service or unauthorized control.
Mitigation Recommendations
No patch or official fix is currently documented for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, network-level protections such as isolating devices and encrypting MQTT traffic externally may reduce risk.
