205-208: Excellent work on improving the security of the file extraction process!The introduction of the
sanitizeExtractPathfunction to sanitize the extraction path, along with the error handling, enhances the robustness and security of the code. This change effectively mitigates potential vulnerabilities that could arise from improper path handling.Tools

241-241: Good simplification of the renaming operation.Using the sanitized path (
originalDir) directly in theos.Renamefunction call improves the clarity and maintainability of the code. It eliminates the need to reconstruct the path, reducing the chances of introducing path-related bugs or inconsistencies.

Consider adding test coverage for the error handling path.
The static analysis tool codecov/patch reported that line 207, which is part of the error handling block in the unzipFile function, is not covered by tests. To ensure the robustness of the code and catch potential issues, it's recommended to add test cases that trigger the error path and verify the expected behavior.
Do you want me to generate a test case for this scenario or open a GitHub issue to track this task?
