Vulnerability from cvelistv5

Severity ?
7.1 (High) - CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
Summary
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.

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."
