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**.","cvssScore":4.8,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","cwes":["CWE-330"],"vendors":[],"products":[],"references":[{"url":"https://nodejs.org/en/blog/vulnerability/october-2026-security-releases","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
