  "description": "crypto.randomUUID() and randomInt() entropy caches are saved into user-land startup snapshots and SEAs, so every process repeats the same values",
  "overview": "A flaw in Node.js `crypto` causes the internal entropy caches used by `crypto.randomUUID()`, `crypto.randomUUIDv7()`, and `crypto.randomInt()` to be saved into user-land startup snapshots (`--build-snapshot`) and single executable applications built with `useSnapshot`.\n\nIf any of these functions, or an API that relies on them such as `URL.createObjectURL()`, is called while the snapshot is built, every process started from that snapshot returns the same values until the cache is refilled: up to 127 UUIDs and about 1,000 `randomInt()` values. 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**.",
