Lifecycle Timeline
8DescriptionCVE.org
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.
AnalysisAI
Langflow up to version 1.8.3 stores authentication settings in cleartext on disk when processing project creation requests, allowing authenticated remote attackers to read sensitive credentials. The vulnerability exists in the create_project/encrypt_auth_settings function within the Project Creation Endpoint, where the auth_settings parameter bypasses encryption despite the function's intent. …

Vulnerability AssessmentAI
| Exploitation | An authenticated Langflow user account is required to invoke the project creation endpoint; the vulnerability cannot be exploited by unauthenticated remote attackers. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS score of 4.3 with vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N reflects low-to-moderate severity: network-accessible, low attack complexity, and low confidentiality impact, but requiring prior authentication (PR:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A legitimate Langflow user with valid authentication credentials creates a new project and supplies third-party service authentication details (e.g., OpenAI API key, database password) via the auth_settings parameter. Instead of being encrypted and stored securely, these credentials are written in plaintext to the project configuration file on the server's filesystem. … |
| Remediation | No vendor-released patch has been identified at time of analysis, and the vendor has not responded to early disclosure attempts. … Detailed patch versions, workarounds, and compensating controls in full report. |
