Description

Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to version 1.7.0, if an arbitrary path is specified in the request body's `fs_path`, the server serializes the Flow object into JSON and creates/overwrites a file at that path. There is no path restriction, normalization, or allowed directory enforcement, so absolute paths (e.g., /etc/poc.txt) are interpreted as is. Version 1.7.0 fixes the issue.

Affected products

• IBM Langflow OSS: before 1.7.0 — fixed in 1.7.0

How to fix

Upgrade to a fixed version: IBM Langflow OSS 1.7.0. Check the vendor advisory for mitigations.
