CVE-2026-106074
Published:October 23, 2026
Updated:October 23, 2026
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".
If 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.
This vulnerability affects Node.js 26.x, 24.x, and 22.x.
