Langflow is a tool for building and deploying AI-powered agents and workflows. In the CSV Agent node, the variable `allow dangerous code` is hardcoded to `True`, which automatically exposes LangChain's Python REPL tool (`python repl ast`). This allows an attacker to execute arbitrary Python and operating system commands on the server through prompt injection, leading to full Remote Code Execution (RCE). Additionally, some reports indicate a deserialization flaw in the flow import endpoint where malicious YAML payloads can be used to execute arbitrary code without authentication. Over 3,000 instances have been identified globally.
