Detailsinfo

A vulnerability has been found in Node.js up to 20.19.6/22.21.1/24.12.0/25.2.1 and classified as critical. Affected by this vulnerability is an unknown code. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

It is possible to read the advisory at nodejs.org. This vulnerability is known as CVE-2025-55130 since 08/07/2025. The exploitation appears to be easy. The attack can be launched remotely.
