Affected: langflow-ai langflow

Langflow is a tool for building and deploying AI-powered agents and workflows. A privilege escalation vulnerability exists in Langflow containers where an authenticated user with RCE access can invoke the internal CLI command langflow superuser to create a new administrative user. This results in full superuser access, even if the user initially registered through the UI as a regular (non-admin) account. A patched version has not been made public at this time.

 https://cve.radiocsirt.org/vuln/ghsa-4gv9-mp8m-592r GHSA-4gv9-mp8m-592r — Langflow Vulnerable to Privilege Escalation via CLI Superuser Creation (Post-RCE) 2026-10-14T16:01:52.092360+00:00

Affected: PyPI: langflow, PyPI: langflow-base

This vulnerability was discovered by researchers at **Check Point**. We are sharing this report as part of a responsible disclosure process and are happy to assist in validation and remediation if needed.

### Summary A privilege escalation vulnerability exists in Langflow containers where an authenticated user with RCE access can invoke the internal CLI command **langflow superuser** to create a new administrative user. This results in full superuser access, even if the user initially registered through the UI as a regular (non-admin) account.

### Details Langflow's Docker image includes a CLI binary at /app/.venv/bin/langflow that exposes sensitive commands, including:

`langflow superuser`

This command allows creation of a new superuser without checking whether one already exists.

When combined with code execution (e.g., via the authenticated **/api/v1/validate/code** endpoint), a low-privileged user can execute:

`/app/.venv/bin/langflow superuser`

inside the container, and elevate themselves to full superuser privileges.

This effectively bypasses frontend role enforcement and backend user integrity, leading to full compromise of the Langflow application.

### PoC 1. Start container with LANGFLOW_ENABLE_AUTH set to True. 2. Visit http://localhost:7860 and sign up. (Your user will not be marked is_superuser.)
