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**."}], "lastModified": "2026-10-23T19:42:24.553", "sourceIdentifier": "support@hackerone.com"}
