Description
The CSV Agent node in Langflow hardcodes allow_dangerous_code=True, which automatically exposes LangChain's Python REPL tool (python_repl_ast). As a result, an attacker can execute arbitrary Python and OS commands on the server via prompt injection, leading to full Remote Code Execution (RCE).
Module options
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
