  • Check exposure: Langflow Unauthenticated Code Execution (CVE-2025-3248). Anyone running Langflow (or langflow-base) older than 1.3.0 / 0.3.0, especially instances reachable from the internet or shared networks, including shadow-IT and demo deployments.
  • Do you run any of these? CrushFTP CrushFTP. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2025-04-28.
  • PyPI: 1 critical advisory (lnbits). Check with pip-audit (or: pip show <package>).
  • None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

Langflow Unauthenticated Code Execution (CVE-2025-3248)

Fixed in March 2025 and exploited in the wild since; if any Langflow below 1.3.0 is reachable from the internet, treat it as compromised, not merely unpatched.

Must act: Anyone running Langflow (or langflow-base) older than 1.3.0 / 0.3.0, especially instances reachable from the internet or shared networks, including shadow-IT and demo deployments.

Can relax: Teams that do not use Langflow, or that run 1.3.0 or later with the server kept off the public internet.

  1. Find every instance: pip show langflow in virtualenvs, docker ps / image tags for langflowai/langflow, and an external scan of your IP space for the Langflow UI.
  2. Upgrade to Langflow 1.3.0 or later (pip install -U langflow), preferably the current release.
  3. Take Langflow off the public internet; put it behind VPN, SSO or an authenticating proxy in an isolated network.
