This PR fixes python.lang.security.audit.exec-detected.exec-detected--tmp-92822dc1-c1d4-4d13-b3b6-328397eac28a-pandasai-core-code_execution-code_executor.py.

---

Important

Enhances security in CodeExecutor by restricting execution environment and improving error handling.

• Security:
  • Restricts execution environment in CodeExecutor by removing eval, exec, compile, and __import__ from built-ins.
  • Uses ast.parse() to validate code before execution.
• Functionality:
  • Replaces global environment with restricted_globals and local_namespace for safer execution.
  • Returns CodeExecutionResult with detailed error information on failure.
• Misc:
  • Removes add_to_env, execute_and_return_result, and environment methods from CodeExecutor.

1. pandasai/core/code_execution/code_executor.py:42

• Draft comment:
  Injecting context variables directly into globals may lead to key collisions. Verify context variable names to avoid overriding built-ins.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 10% vs. threshold = 50% The code is actually well-designed for safety. It first creates a restricted globals with only safe built-ins, then adds context variables. Even if there was a collision, it would only override the restricted copy, not the actual built-ins. The code is already following security best practices. The comment raises a valid security concern that developers should be aware of. Could there still be issues if malicious context variables override important restricted built-ins? While security concerns are important, the code's design already handles this safely by using a restricted copy of built-ins. Any overrides would only affect the local execution context, not the actual Python environment. The comment should be removed as the code already implements proper safety measures for handling potential built-in collisions through its restricted globals implementation.

2. pandasai/core/code_execution/code_executor.py:32

• Draft comment:
  Consider using a whitelist of safe builtins instead of blacklisting functions (eval, exec, compile, import) for a more robust security model.
• Reason this comment was not posted:
  Marked as duplicate.

3. pandasai/core/code_execution/code_executor.py:63

• Draft comment:
  Consider logging exception details in the error handler for easier debugging in production.
• Reason this comment was not posted:
  Confidence changes required: 50% <= threshold 50% None

4. pandasai/core/code_execution/code_executor.py:19

• Draft comment:
  Ensure that unit tests are added for the new 'execute' method to cover both successful execution and error handling scenarios.
• Reason this comment was not posted:
  Marked as duplicate.

[ellipsis-dev]

Consider whitelisting only safe built-in functions rather than excluding a few (eval, exec, compile, __import__) — this can reduce the risk of bypassing restrictions.

[ellipsis-dev]

Ensure there are corresponding unit tests for this new execute() implementation to cover both successful and error execution paths.
