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,...
