# Duplicate Advisory : Flowise allows arbitrary file write to RCE

Flowise, an AI workflow builder, has a path traversal flaw in its document-store loader endpoint that lets unauthenticated users write arbitrary files. An attacker can overwrite files such as package.json so that code runs when the application restarts.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- npm:flowise affected <= 2.2.7 fixed ?

## How to check

- Check the installed Flowise version with `npm ls flowise` and compare it to the affected range `<= 2.2.7`
- Look for exposure of the `/api/v1/document-store/loader/process` endpoint on internet-facing Flowise servers

## From the sources

### Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-8vvx-qvq9-5948. This link is maintained to preserve external references.

### Original Description

Flowise contains a path traversal vulnerability in the /api/v1/document-store/loader/process endpoint that allows unauthenticated attackers to write arbitrary files to the filesystem. Attackers can exploit unsanitized fileName parameters with ../ sequences to overwrite critical files like package.json and achieve remote code execution when the application restarts.
