{"id":"ALPINE-CVE-2026-106074","details":"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**.","modified":"2026-10-24T09:30:02.643742379Z","published":"2026-10-23T17:17:20.473Z","upstream":["CVE-2026-106074"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-106074"}],"affected":[{"package":{"name":"nodejs","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"22.23.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-106074.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"22.23.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-106074.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"24.22.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-106074.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"24.22.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-106074.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
