Overview

flowise is a Flowiseai Server

Affected versions of this package are vulnerable to Arbitrary Code Injection via the run method in the CSV_Agents class. An attacker can execute arbitrary code in the context of the server process by sending crafted prompts to a chatflow using the CSV Agent node, which causes the LLM to generate malicious Python code that bypasses input validation and is executed in an unsandboxed environment.
