mqtt authorization

The mqtt authorization tag covers discussions about weaknesses in MQTT-based authorization mechanisms, particularly in IoT and cloud-connected devices. Content highlights how hard-coded credentials and weak authorization in MQTT infrastructure can expose fleet telemetry and allow unauthorized command execution, as seen in a CISA advisory about Yarbo robots. The tag draws parallels to enterprise IT security lessons, emphasizing that shared identities and ornamental authorization turn cloud systems into a single blast radius. Topics include MQTT security, credential management, and authorization flaws in device fleets.
