Summary
Flowise's CSVAgent node runs user-supplied Python through pyodide, intended for pandas CSV processing. A denylist blocks dangerous constructs, but the user-controlled customReadCSVFunc input can call pandas.read_pickle(), which deserializes a pickled payload and allows code execution without matching any denied pattern.
Mitigation
The source does not state a fix yet. Check the original advisory for updates.
