High/Medium Severity Security Vulnerabilities (RCE via eval, Insecure Temp Dir)

[HarshavardhanVemali]

A secondary security audit using bandit revealed additional vulnerabilities in this repository that should be addressed.

1. Remote Code Execution (RCE) via eval()

Using eval() on untrusted input from an LLM or user allows arbitrary Python code execution.

• Crewai-agents/trip_planner/tools/calculator_tools.py: The calculate tool calls eval(operation) on raw string inputs.
• anthropic-quickstart/03-function-calling-agent/claude_function_agent.py: Uses eval() for math evaluation. While __builtins__ is cleared, eval is notoriously difficult to sandbox and can still be bypassed.
  Recommendation: Restrict the evaluation to basic math operations or use a safer alternative like ast.literal_eval or strict regex validation.

2. Insecure Temporary Directory Usage

Hardcoding /tmp is flagged by security scanners as it can lead to symlink attacks or predictable paths on shared systems.

• openclaw/fetchai-openclaw-orchestrator/connector/policy.py: Hardcodes "/tmp".
  Recommendation: Use tempfile.gettempdir() instead.

3. Vulnerable urllib.urlopen Usage

The urllib.request.urlopen function is prone to protocol injection vulnerabilities if the URL is somewhat dynamic.

• openclaw/agentverse-caller/scripts/call.py
• Claude Agent SDK/real-estate-search-agent/sheets.py
  Recommendation: Use the safer requests library instead of urllib.
