Technical details
CVE-2026-69658 is a cleartext transmission vulnerability in the Ebyte NE2-D11 web management interface, where MQTT credentials and control traffic are sent unencrypted over the network. The root cause is inadequate protection of sensitive communications; the device fails to enforce transport-layer encryption (TLS/SSL) for authentication and session-related information. An attacker with network-level access can passively intercept packets to capture credentials and session tokens, or actively impersonate the device or authenticated users. No authentication or user interaction is required; exploitation works on unpatched firmware FW-9167-0-11. Ebyte acknowledged the vulnerability and indicated a patch was under development, but has not provided status updates or released a fix to CISA.
