CVE-2026-54609: CWE-400: Uncontrolled Resource Consumption in Quiet-Terminal-Interactive QTINeon
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.
AI Analysis
Technical Summary
QTINeon 1.0.0 contains an uncontrolled resource consumption vulnerability (CWE-400) due to the relay's handleReconnectRequest forwarding RECONNECT_REQUEST packets without bounding. This flaw enables unauthenticated clients to amplify traffic from the relay to the host, potentially causing a denial of service on the host system. The vulnerability is categorized under CWE-400 (Uncontrolled Resource Consumption), CWE-406 (Insufficient Control of Network Message Volume), and CWE-770 (Allocation of Resources Without Limits or Throttling). As of the current review, no official remediation or patch has been released.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to cause a denial of service on the host by driving relay-to-host amplification through unbounded RECONNECT_REQUEST packets. This results in resource exhaustion on the host, impacting availability. There is no impact on confidentiality or integrity reported.
Mitigation Recommendations
No official fix or patch is currently available for this vulnerability. Users should monitor vendor advisories for updates. Until a patch is released, consider implementing network-level rate limiting or filtering of RECONNECT_REQUEST packets to mitigate potential amplification attacks. Avoid exposing the relay service to untrusted networks if possible.
