Prior to 3.1.3, the CSVAgent node allowed users to provide Python code that is executed through pyodide; although a denylist blocked dangerous Python constructs, pandas.read_pickle() could deserialize a pickled payload and achieve code execution without matching the denied words. The affected file is flowise-components/nodes/agents/CSVAgent/CSVAgent.ts, where user-supplied customReadCSVFunc is evaluated as pd.${customReadCSVFunc}. An authenticated user who can create or modify a chatflow can add a CSV Agent, place a malicious read_pickle payload in the Additional Parameters, save the chatflow, and trigger /api/v1/prediction/<UUID> to execute commands. This issue is fixed in version 3.1.3."},{"lang":"es","value":"Flowise es una interfaz de usuario de arrastrar y soltar para construir un flujo de modelo de lenguaje grande personalizado. Antes de la versión 3.1.3, el nodo CSVAgent permitía a los usuarios proporcionar código Python que se ejecuta a través de pyodide; aunque una lista de denegación bloqueaba construcciones peligrosas de Python, pandas.read_pickle() podía deserializar una carga útil ’pickled’ y lograr la ejecución de código sin coincidir con las palabras denegadas.
