What is CVE-2026-72586?
CVE-2026-72586 is a high-severity missing authorization vulnerability in frangoteam FUXA, published on 10 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-306
