Loading vulnerability…
CVE-2026-69264 is a critical code-injection vulnerability in Flowise and flowise-components versions earlier than 3.1.3 affecting CSVAgent. An attacker-controlled portion of a CSV data URI is directly interpolated into a Python source template executed by Pyodide. The bootstrap template is not covered by the relevant Python and custom CSV-function validation paths. On Node.js deployments, Pyodide's default JavaScript bridge exposes access to JavaScript evaluation and dynamic module loading, allowing an attacker to escape the intended Python string context and invoke Node.js capabilities from the Flowise process.

Remote code execution vulnerability in the Flowise CSVAgent component via attacker-controlled content injection into Python code executed through Pyodide.
A critical remote code execution vulnerability in Flowise CSVAgent where attacker-controlled csvFile data is interpolated into executed Python code, enabling breakout to JavaScript via Pyodide and arbitrary file I/O or OS command execution as the Flowise process.
Critical unauthenticated remote code execution vulnerability in Flowise CSVAgent caused by unsafe interpolation of attacker-controlled CSV data into Pyodide-executed Python code, enabling JavaScript bridge escape and Node.js file-system or OS-command execution.
