Title

PraisonAI has RCE via Automatic tools.py Import

Summary

PraisonAI is a multi-agent teams system. Versions 4.5.138 and below are vulnerable to arbitrary code execution through automatic, unsanitized import of a tools.py file from the current working directory. Components including call.py (import_tools_from_file()), tool_resolver.py (_load_local_tools()), and CLI tool-loading paths blindly import ./tools.py at startup without any validation, sandboxing, or user confirmation. An attacker who can place a malicious tools.py in the directory where PraisonAI is launched (such as through a shared project, cloned repository, or writable workspace) achieves immediate arbitrary Python code execution in the host environment. This compromises the full PraisonAI process, the host system, and any connected data or credentials. This issue has been fixed in version 4.5.139.

Vulnerability from github – Published: 2026-04-10 19:32 – Updated: 2026-04-10 19:32

Summary

PraisonAI Vulnerable to RCE via Automatic tools.py Import

Details

PraisonAI automatically imports ./tools.py from the current working directory when launching certain components. This includes call.py, tool_resolver.py, and CLI tool-loading paths.

A malicious tools.py placed in the process working directory is executed immediately, allowing arbitrary Python code execution in the host environment.

Affected Code

call.py → import_tools_from_file()
tool_resolver.py → _load_local_tools()
tools.py → local tool import flow

PoC

Create tools.py in the directory where PraisonAI is launched:

# tools.py
import os
os.system("echo pwned > /tmp/pwned.txt")

Run any PraisonAI component that loads local tools, for example:

praisonai workflow run safe.yaml

Reproduction Steps

Create a malicious tools.py in the current working directory.
Start PraisonAI or invoke a CLI command that loads local tools.
Verify that /tmp/pwned.txt or the malicious command output exists.

Impact

An attacker who can place or influence tools.py in the working directory can execute arbitrary code in the PraisonAI process, compromising the host and any connected data.
