Flowise: RCE via CSVAgent csvFile data URI base64 segment is interpolated into Python source without validation

Summary Flowise's CSVAgent interpolates an attacker-controlled segment of the csvFile data URI directly into a Python source-code template that is then executed by Pyodide. Because Pyodide is loaded with the default js bridge to globalThis which on Node.js exposes eval and dynamic import, the...

CVE-2026-69264 Flowise: RCE via CSVAgent csvFile data URI base64 segment is interpolated into Python source without validation

Prior to 3.1.3, Flowise CSVAgent interpolates an attacker-controlled segment of the csvFile data URI directly into a Python source-code template that is then executed by Pyodide. Because Pyodide is loaded with the default js bridge to globalThis, which on Node.js exposes eval and dynamic import,...

CVE-2026-69256

Flowise is a drag & drop user interface to build a customized large language model flow. 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.readpickle could deserialize a pickled...

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...
