PYSEC-2026-2914

HighCVSS 8.4 / 10
Published Jul 13, 2026·Last modified Jul 13, 2026
Affected Components(0)

No affected components available

Description

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

  1. Create a malicious tools.py in the current working directory.
  2. Start PraisonAI or invoke a CLI command that loads local tools.
  3. 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.
