{"id":"BIT-node-min-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.\nThis vulnerability affects users of the permission model on Node.js v20,  v22,  v24, and v25.","aliases":["BIT-node-2025-55130","CVE-2025-55130"],"modified":"2026-02-04T10:30:16.581180Z","published":"2026-01-26T14:47:50.037Z","database_specific":{"severity":"Critical","cpes":["cpe:2.3:a:nodejs:node.js:*:*:*:*:*:*:*:*"]},"references":[{"type":"WEB","url":"https://nodejs.org/en/blog/vulnerability/december-2025-security-releases"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-55130"}],"affected":[{"package":{"name":"node-min","ecosystem":"Bitnami","purl":"pkg:bitnami/node-min"},"ranges":[{"type":"SEMVER","events":[{"introduced":"20.0.0"},{"fixed":"20.20.0"},{"introduced":"21.0.0"},{"fixed":"22.22.0"},{"introduced":"23.0.0"},{"fixed":"24.13.0"},{"introduced":"25.0.0"},{"fixed":"25.3.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/node-min/BIT-node-min-2025-55130.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}],"schema_version":"1.7.3"}
