Affected packages
• PyPI praisonaiagents: < 1.5.140 → fixed in 1.5.140
• PyPI PraisonAI: < 4.5.139 → fixed in 4.5.139
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:
```python
tools.py
import os
os.system("echo pwned > /tmp/pwned.txt")
```
Run any PraisonAI component that loads local tools, for example:
```bash
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.
