This is an incomplete fix of CVE-2026-48931.\n\nThe guard that destroys idle keep-alive sockets when unexpected data arrives only runs when the event loop polls for I/O. If an unsolicited response has already reached the socket but has not been read yet when the socket is handed to a new request, for example because the event loop was busy with synchronous work, the guard is removed without seeing it and the data is parsed as the response to the new request.\n\nThis vulnerability affects Node.js **26.x**, **24.x**, and **22.x**.","state":0,"publishedAt":"2026-10-23T16:15:05.837+00:00","modifiedAt":"2026-10-23T16:15:05.837+00:00","affected":[{"ecosystem":"Vendor product","name":"node","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"nodejs\",\n                    \"product\": \"node\",\n                    \"versions\": [\n                        {\n                            \"version\": \"22.23.3\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"22.23.3\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"24.22.0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"24.22.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"26.12.0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"26.12.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.0","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://nodejs.org/en/blog/vulnerability/october-2026-security-releases"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-105481","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-105481","identifiers":["CVE-2026-105481"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
