Thank you for your work on integrating EventBridge Scheduler functionality and updating the packaging scripts. However, there are several critical security issues and areas for improvement that need to be addressed before this pull request can be approved:
-
Input Validation: The EventBridge Scheduler integration lacks robust input validation, which could lead to security vulnerabilities.
-
Unimplemented Core Functionality: The
createSchedulemethod in the EventBridgeSchedulerService is not yet implemented, which is crucial for the feature to work. -
Critical Security Vulnerabilities: The
clean.tsscript contains multiple severe security issues, including hardcoded credentials, command injection, path traversal, and SQL injection vulnerabilities. These must be addressed immediately. -
Insecure File Download: The
downloadFilesfunction inpackage.tshas potential security implications and needs to be refactored for better security and error handling.
Please address these issues, focusing particularly on resolving the security vulnerabilities. Once these changes are made, we can re-review the pull request. If you need any clarification or assistance with implementing secure solutions, please don't hesitate to ask.

🛑 Security Vulnerability: The input validation for the schedule name is not robust enough. It allows empty strings and doesn't enforce a minimum length, which could lead to potential security risks1. Consider enhancing the validation to ensure a minimum length and prevent empty inputs.

The createSchedule method is currently throwing an error indicating that the EventBridge Scheduler integration is not yet implemented. It's important to implement this method to provide the core functionality of creating schedules. Consider prioritizing the implementation of this method to interact with the AWS EventBridge Scheduler API.

🛑 Critical Security Vulnerabilities: This code contains multiple severe security issues:
- Hardcoded credentials (API key, password, database connection string)1
- Command injection vulnerability in the
executeCommandfunction2 - Path traversal vulnerability in the
readUserFilefunction3 - SQL injection vulnerability in the query string4
These issues pose significant security risks and must be addressed immediately.

The downloadFiles function has potential security implications:
- It only checks for the Linux platform, which might lead to unexpected behavior on other platforms.
- It uses
child_process.execFileSyncto runcurl, which could be a security risk if theurlparameter is not properly sanitized1. - The function silently ignores any errors during the download process, which could lead to incomplete or corrupted files without any warning.
Consider implementing more robust error handling, input validation, and using a more secure method for downloading files, such as a trusted HTTP client library.
