Vulnerability details
The vulnerability allows a remote attacker to predict values expected to be random in one process by observing values produced by another process started from the same snapshot.
The vulnerability exists due to reuse of cached random data in Node.js crypto.randomUUID(), crypto.randomUUIDv7(), and crypto.randomInt() when their entropy caches are saved into startup snapshots and restored across processes. A remote attacker can observe outputs from another process using the same snapshot to predict repeated values in a target process before its cache is refilled.
