Kerentanan Improper Control of Generation of Code ('Code Injection') pada langflow. Skor CVSS 3.1 9.8 (Critical) menurut github.com.

Deskripsi (NVD)

Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to version 1.8.0, the CSV Agent node in Langflow hardcodes `allow_dangerous_code=True`, which automatically exposes LangChain’s Python REPL tool (`python_repl_ast`). As a result, an attacker can execute arbitrary Python and OS commands on the server via prompt injection, leading to full Remote Code Execution (RCE). Version 1.8.0 fixes the issue.
