CVE-2026-54609
CVE-2026-54609 · QTINeon has unauthenticated relay-to-host amplification via unbounded RECONNECT_REQUEST forwarding
This page contains facts from public vulnerability sources. Check the original advisory before updating.
QTI Neon is a minimal, game-agnostic, relay-based UDP multiplayer protocol library. In version 1.0.0, the relay's handleReconnectRequest forwards RECONNECT_REQUEST packets to the host without bounding them, so an unauthenticated client can drive relay-to-host amplification and cause a denial of service on the host. No fixed version is available as of this review.
