Description

A missing authentication vulnerability in frangoteam/FUXA through 1.3.3 allows an unauthenticated remote attacker to query all historical sensor data via the DAQ_QUERY Socket.IO event. When secureEnabled=true, all other sensitive Socket.IO events (DEVICE_BROWSE, HOST_INTERFACES, DEVICE_TAGS_REQUEST, etc.) call isSocketAdminAuthorized to verify the connection token, but the DAQ_QUERY handler in server/runtime/index.js lacks this check entirely.
