The affected element is an unknown function of the file traceroute.cmd. The manipulation leads to denial of service. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The presence of this vulnerability remains uncertain at this time. The vendor explains: \"After reviewing the researcher's videos, we repeated the test using his described setup: the traceroute cancel request was sent while a second client was connected to the EWI. The second client remained connected and was not interrupted, and we did not observe a forced logout, session invalidation, or loss of EWI availability.\"","state":0,"publishedAt":"2026-08-13T19:15:07.554+00:00","modifiedAt":"2026-10-16T06:04:51.525+00:00","affected":[{"ecosystem":"Vendor product","name":"GigaSpire","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Calix\",\n                    \"product\": \"GigaSpire\",\n                    \"versions\": [\n                        {\n                            \"version\": \"26.1.0\",\n                            \"status\": \"affected\"\n                        }\n                    ],\n                    \"cpes\": [\n                        \"cpe:2.3:a:calix:gigaspire:*:*:*:*:*:*:*:*\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","score":5.3,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:P/RL:X/RC:R","score":4.3,"severity":"MEDIUM"},{"system":"CVSS 3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:P/RL:X/RC:R","score":4.3,"severity":"MEDIUM"},{"system":"CVSS 2.0","vector":"AV:N/AC:L/Au:S/C:N/I:N/A:P/E:POC/RL:ND/RC:UR","score":4,"severity":null}],"references":["https://vuldb.com/vuln/389484","https://vuldb.com/vuln/389484/cti","https://vuldb.com/cve/CVE-2026-19746","https://vuldb.com/submit/868299"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-19746","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-19746","identifiers":["CVE-2026-19746"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
