CVE-2025-68478

Langflow Vulnerable to External Control of File Name or Path

State: Published
Severity: 7.1 High
Published: Dec 19, 2025
Updated: Dec 19, 2025
Reserved: Dec 18, 2025

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.
