Thank you for your work on implementing the EventBridge Scheduler functionality and updating the packaging scripts. However, there are several critical security issues that need to be addressed before this pull request can be approved:
-
In the EventBridge Scheduler implementation:
- Improve input validation for schedule names and cron expressions.
- Ensure proper input sanitization in the
createSchedulemethod when it's implemented.
-
In the
clean.tsscript:- Remove hardcoded credentials and use environment variables instead.
- Fix the command injection vulnerability in the
executeCommandfunction. - Address the path traversal vulnerability in the
readUserFilefunction. - Use parameterized queries to prevent SQL injection.
-
In the
package.tsscript:- Implement security measures in the
preparePackagerfunction, including integrity checks for downloaded files and proper error handling.
- Implement security measures in the
Please address these security concerns and update the pull request. Once these issues are resolved, we can proceed with a more detailed review of the EventBridge Scheduler implementation. If you need any clarification or assistance with implementing the suggested fixes, please don't hesitate to ask.

Consider adding input validation for the schedule name. While you're checking for length and allowed characters, it's also important to ensure the name doesn't start with 'aws-' as this prefix is reserved for AWS-managed schedules1.

The cron expression validation is currently only checking for the number of fields. Consider implementing a more robust validation to ensure the cron expression is valid and follows the EventBridge Scheduler syntax1. This can help prevent runtime errors and improve user experience.

🛑 Security Vulnerability: Hardcoded credentials and sensitive information have been added to the code. This is a severe security risk and violates best practices1. Never store sensitive information directly in the source code, even for private demos. Instead, use environment variables or secure secret management systems.

The preparePackager() function introduces potential security risks:
- It downloads a file from a GitHub repository without verifying its integrity1.
- It overwrites an existing file (
extensionNode.ts) without backup or version control2. - The function runs only in production environments, which could lead to unexpected behavior in production if the downloaded file is malicious or corrupted.
Consider implementing the following security measures:
- Use HTTPS for downloads and verify the SSL/TLS certificate.
- Implement integrity checks (e.g., checksum verification) for downloaded files.
- Use version control or backup the existing file before overwriting.
- Implement proper error handling and logging for the download process.
- Consider using a more secure method for updating production code, such as through your CI/CD pipeline.
