Prior to 1.10.0, the \"Shareable Playground\" (or \"Public Flows\" in code) contains a potential arbitrary file-read vulnerability, depending on the exact flow configuration used. By making a flow public, public execution of the flow is allowed. The execution request can contain a list of files that gets read by Langflow and fed into the LLM.
