CVE-2026-54609
Last modified
CVE-2026-54609 is a high-severity vulnerability rated 8.6/10 on the CVSS scale. 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. EPSS estimates a 0.26% chance of exploitation in the next 30 days.
