Langflow Ai · Langflow · CVE-2026-6596
**Name of the Vulnerable Software and Affected Versions**
langflow-ai langflow versions prior to 1.1.1
**Description**
An unrestricted file upload flaw exists in the API Endpoint component. The issue is located in the `create upload file()` function within the file 'src/backend/base/Langflow/api/v1/endpoints.py'. This allows a remote attacker to upload files without proper restrictions. Over 2,900 internet-facing instances have been identified as potentially exposed.
**Recommendations**
Update to a version later than 1.1.0.
As a temporary workaround, restrict access to the `create upload file()` function until a patch is applied.
