RealGround Analysis
Langflow sits at the centre of agent workflows and usually holds API keys for models and tools, so compromising it exposes everything the agents can reach. RealGround analysis: AI orchestration platforms belong in the same patch and exposure programme as any internet-facing app server.
Recommended Controls
- Patch Langflow to a fixed version
- Do not expose Langflow to the internet; put it behind authentication and network controls
- Rotate API keys stored in Langflow if exposure is suspected
- List Langflow and its version in the AI SBOM
