CVE-2026-46459

Configuration disclosure and sensor writes via unauthenticated endpoints

Published Jul 15, 2026 · Updated Jul 15, 2026

Missing authorization in ICU Scandinavia Boomerang before 2.4.18.029 allows remote attackers to read configurations and write sensor data. Device receiver endpoints accept configuration reads and sensor database writes without applying any authentication mechanism. Network reachability to those endpoints is sufficient, exposing full facility configurations and allowing falsified sensor records.
