Langflow's Agentic Assistant feature, prior to version 1.9.0, executes LLM-generated Python code during validation. This implementation allows for arbitrary server-side Python execution if an attacker can access the Agentic Assistant feature and influence the model output. The vulnerable code path involves processing model output through a chain that ultimately invokes `create class()`, which dynamically executes Python code using `exec()`. The affected endpoints include `/api/v1/login` and the assistant feature relies on user authentication via bearer token, cookie, or API key. Default deployment settings, such as `AUTO LOGIN=true` and the `/api/v1/auto login` endpoint, may widen exposure. The issue is an authenticated code execution vulnerability, with severity depending on the deployment model.
