CVE-2026-51745Network attack vector

Unauthenticated station-list refresh via crafted MQTT message

Published Sep 1, 2026 · Updated Sep 1, 2026

Incorrect access control in TOTOLINK T6 4.1.5cu.748_B20211015 allows remote attackers to refresh the primary station list via MQTT. The cs_broker component accepts a message with topicurl set to updatePriStaList without authentication, then wireless.so invokes that function and refreshes the list. Network access to the MQTT broker is required, and the documented consequence is limited to forcing this station-list refresh rather than changing other configuration.
