AI-analyzed exploit summary This repository contains a working proof-of-concept exploit for CVE-2025-55130, a Node.js permission model bypass vulnerability. The exploit leverages symlinks and path traversal to escape sandbox restrictions imposed by `--allow-fs-read` and `--allow-fs-write` flags.
Description
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.
