Arbitrary Code Injection

langflow is an A Python package with a built-in web application

Affected versions of this package are vulnerable to Arbitrary Code Injection through any components that provided the code functionality running on the local machine rather than a sandboxed environment. An attacker can execute arbitrary code on the host system by injecting malicious code into the components.

Missing Authorization

langflow is an A Python package with a built-in web application

Affected versions of this package are vulnerable to Missing Authorization due to improper authorization checks to verify flow ownership in upload_file function in files.py file. To exploit this vulnerability, an attacker needs valid authentication credentials but does not require elevated privileges.

Note: The attack can be carried out by sending file upload requests to the /api/v1/files/upload endpoint with a flow_id parameter corresponding to another user's flow.

How to fix Missing Authorization?

Upgrade langflow to version 1.0.19 or higher.
