PraisonAI before 1.6.78 contains a remote code execution vulnerability in SkillTools.run_skill_script() that executes scripts without path containment validation. Attackers can supply absolute file paths to execute arbitrary scripts from any filesystem location, including those outside the intended working directory.

GHSA-c44f-37qr-gw3f — PraisonAI: SkillTools Executes Scripts Without Path Containment Validation

Affected: PyPI: praisonaiagents

### Summary `SkillTools.run_skill_script()` accepts a `script_path` parameter and executes it via `subprocess.run()` without any path containment validation. While `FileTools` has `_validate_path()` with traversal detection, `SkillTools` performs none. An LLM-directed call can execute arbitrary scripts from any filesystem location. The `@require_approval` decorator can be bypassed via YAML `approve:` for high-risk tools.

### Details `src/praisonai-agents/praisonaiagents/tools/skill_tools.py` (lines 69-119):

```python def run_skill_script(self, script_path: str, ...): script_path = os.path.expanduser(script_path) if not os.path.isabs(script_path): script_path = os.path.join(self._working_directory, script_path) script_path = os.path.abspath(script_path)

if not os.path.exists(script_path): return f"Error: Script not found at {script_path}"

# No path traversal check, no containment validation # Directly executes whatever is at that path: result = subprocess.run(cmd, ...) ```

By contrast, `FileTools._validate_path()` (`src/praisonai-agents/praisonaiagents/tools/file_tools.py`, lines 42-78) properly validates that the resolved path stays within the working directory:

```python def _validate_path(self, filepath: str) -> str: # ... cwd = os.path.abspath(os.getcwd()) if os.path.commonpath([absolute, cwd]) != cwd: raise ValueError(f"Path traversal detected: {filepath} escapes workspace {cwd}") ```
