Identifiers expected to be unique can collide across processes, and values issued by one process can be predicted by observing another.\n\nThis vulnerability affects Node.js **26.x**, **24.x**, and **22.x**.","state":0,"publishedAt":"2026-10-23T16:15:05.829+00:00","modifiedAt":"2026-10-23T16:15:05.829+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:L/A:N","score":4.8,"severity":"MEDIUM"}],"references":["https://nodejs.org/en/blog/vulnerability/october-2026-security-releases"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-106074","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-106074","identifiers":["CVE-2026-106074"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
