{"id":"ALPINE-CVE-2026-106073","details":"A flaw in Node.js Permission Model filesystem enforcement leaves `fs.realpathSync()` without the required read permission checks. This is an incomplete fix of CVE-2026-21715, which only covered `fs.realpathSync.native()`.\n\nAs a result, code running under `--permission` with restricted `--allow-fs-read` can still use `fs.realpathSync()` to check file existence, resolve symlink targets, and enumerate filesystem paths outside of permitted directories.\n\nThis vulnerability affects Node.js **26.x**, **24.x**, and **22.x**.","modified":"2026-10-24T09:30:02.700489345Z","published":"2026-10-23T17:17:20.343Z","upstream":["CVE-2026-106073"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-106073"}],"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-2026-106073.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-2026-106073.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-2026-106073.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-2026-106073.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
