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.","state":0,"publishedAt":"2026-07-28T16:36:37.938+00:00","modifiedAt":"2026-07-28T17:07:15.08+00:00","affected":[{"ecosystem":"Vendor product","name":"QTINeon","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Quiet-Terminal-Interactive\",\n                    \"product\": \"QTINeon\",\n                    \"versions\": [\n                        {\n                            \"version\": \"1.0.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","score":8.6,"severity":"HIGH"}],"references":["https://github.com/Quiet-Terminal-Interactive/QTINeon/security/advisories/GHSA-85rg-p3fr-xc2f"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54609","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54609","identifiers":["CVE-2026-54609"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
