CVE-2026-6598 Details
Description
A security vulnerability has been detected in langflow-ai langflow up to 1.8.3. The affected element is the function create_project/encrypt_auth_settings of the file src/backend/base/Langflow/api/v1/projects.py of the component Project Creation Endpoint. Such manipulation of the argument auth_settings leads to cleartext storage in a file or on disk. The attack can be launched remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A vulnerability exists in Langflow AI's project management feature, specifically in versions up to 1.8.3. The issue arises in the project creation API, where sensitive authentication data, such as API keys and passwords, is stored in plaintext instead of being encrypted. This flaw is due to the encryption function only processing a limited set of predefined fields, leaving other sensitive information exposed. The vulnerability can be exploited remotely, and a public proof-of-concept is available.
