Flowise: Remote Code Execution Vulnerability in CSVAgent

Summary The CSVAgent node was observed to allow users to write Python code which gets executed via pyodide. The original intent was to allow users to utilise the pandas library for CSV processing. Although there is a denylist that checks for dangerous Python constructs from being passed in, panda...

CVE-2026-69256

Flowise CVE-2026-69256 affects the CSVAgent node prior to version 3.1.3. A user-supplied customReadCSVFunc is evaluated as pd.${customReadCSVFunc} and can execute via Pyodide, bypassing a denylist with a pandas.read_pickle payload. An authenticated user who can create/modify a chatflow can add th...
