{"id":"DEBIAN-CVE-2025-55130","details":"A flaw in Node.js’s Permissions model allows attackers to bypass `--allow-fs-read` and `--allow-fs-write` restrictions using crafted relative symlink paths. By chaining directories and symlinks, a script granted access only to the current directory can escape the allowed path and read sensitive files. This breaks the expected isolation guarantees and enables arbitrary file read/write, leading to potential system compromise. This vulnerability affects users of the permission model on Node.js v20,  v22,  v24, and v25.","modified":"2026-09-01T20:05:54.475759617Z","published":"2026-01-20T21:16:03.177Z","upstream":["CVE-2025-55130"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-55130"}],"affected":[{"package":{"name":"nodejs","ecosystem":"Debian:13","purl":"pkg:deb/debian/nodejs?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"20.19.2+dfsg-1+deb13u1"}]}],"versions":["20.19.2+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-55130.json"}},{"package":{"name":"nodejs","ecosystem":"Debian:14","purl":"pkg:deb/debian/nodejs?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"22.22.0+dfsg+~cs22.19.6-1"}]}],"versions":["20.19.2+dfsg-1","20.19.4+dfsg-1","20.19.5+dfsg+~cs20.19.12-1","20.19.5+dfsg+~cs20.19.12-2","20.19.5+dfsg+~cs20.19.12-3","20.19.5+dfsg+~cs20.19.12-4","20.19.5+dfsg+~cs20.19.24-1","22.12.0+dfsg-1","22.12.0+dfsg-2","22.12.0+dfsg-3","22.14.0+dfsg-1","22.18.0+dfsg+~cs22.17.2-1","22.18.0+dfsg+~cs22.17.2-2","22.18.0+dfsg-1","22.19.0+dfsg+~cs22.18.0-1","22.21.1+dfsg+~cs22.19.0-1","22.21.1+dfsg+~cs22.19.0-2","22.21.1+dfsg+~cs22.19.0-3","22.21.1+dfsg+~cs22.19.0-4","22.21.1+dfsg+~cs22.19.0-5","22.21.1+dfsg+~cs22.19.0-6"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-55130.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
