PT-2026-34236

Name of the Vulnerable Software and Affected Versions Flowise versions prior to 3.1.0 Description A flaw exists in the run method of the CSV Agents class due to improper sandboxing when evaluating Python scripts generated by a Large Language Model LLM. An unauthenticated attacker can use prompt...

Flowise: Code Injection in CSVAgent leads to Authenticated RCE

Summary The CSVAgent allows providing a custom Pandas CSV read code. Due to lack of sanitization, an attacker can provide the following payload: DataFrame'foo': 'bar!';import os;os.system'whoami' that will get interpolated and executed by the server. Details The code in question that introduces t...

Langflow has Remote Code Execution in CSV Agent

Summary The CSV Agent node in Langflow hardcodes allowdangerouscode=True, which automatically exposes LangChain’s Python REPL tool pythonreplast. 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...

CVE-2026-27966

Langflow before version 1.8.0 exposes a remote code execution risk through the CSV Agent node by hardcoding allow_dangerous_code=True, which enables Python REPL access (python_repl_ast) via prompt injection. This allows an attacker to execute arbitrary Python/OS commands on the server. The issue ...
