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**.\n\n## Affected\n\n- `node >= 22.23.3 <= 22.23.3`\n- `node >= 24.22.0 <= 24.22.0`\n- `node >= 26.12.0 <= 26.12.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":26,"depthScoreParts":{"impact":26.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
